Town driving–Throttle response is still nice and strong-nothing changed there and that is good. A little jumpy in S# at ~25% throttle around 3K in 2nd and 3rd BUT** it’s very responsive to input and i don’t have the most steady foot on bumpy roads:-) doesn’t do it in S mode so yeah…my foot lol!
3rd gear pull– Only 1 single instance (single cell) of ping (-1.5) right before peak boost. a few -1.5 cells as I lifted off throttle at 6000rpm. Feels Strong.
How it feels on the 3rd gear pull–pulls harder as the boost spools up–perfect!. It feels like it hits a shot of Nitrous about 4600RPM as it transitions from 8.5degrees to 10.5degrees of timing. It’s subtle, not a surge, but I thought I’d point that out.
Roll on acceleration about 3000rpm—amazing in all gears. I don’t really feel that transition in this circumstance.
2nd gear is just nuts. I never really tried it before at WOT. SO yeah, nice one!
Shifting–under load, nice and sharp and quick. I don’t know if it’s possible to tune this—-> but it would be nice for the trans to respond faster to paddle inputs, especially at light load around town. No big deal though;-)
Alright, well where do I start? As we are getting close to the end of the tuning process I’m thoroughly impressed. Ed’s knowledge and feedback to my queries has been fantastic. He’s quick to respond and I challenge any tuner to provide such good customer support! Feedback is nearly immediate and revisions come daily (sometimes more often!).
I urge any Cobb tuned customer to consider XRT. If you have an 5EAT or if you are Cobb tuned on Canadian petrol, you need to contact XRT tomorrow!!
My Cobb stage 2 provided predictable, modest power improvements as advertised from Cobb. However, as predicted, the pinging (feedback knock, fine knock learning) was endemic, over all grades of petrol. Only after a couple revisions he had the power far above Cobb’s tune, and a transmission that provides strong, fast shifts. We are onto Rev 5, and the power keeps building and I’m getting zero pinging under all conditions, on standard Canadian 91 petrol! And the shifting and throttle response are unreal. Night and day over an Off The Shelf tune…. BRAVO Edward!!!!
At first, I had a stage 1 OTS cobb tune and loved it. That opened the car up to what it was capable of and once I realized that, I got hungry for more. I saw a post about XRT and started to get incredibly curious on all the gains someone received from them. Once I emailed XRT(Ed), he informed me BlackBerry Messenger(BBM) is how he chats with all his clients. He is based in the Barbados so we can call each other on BBM or Whatsapp to avoid oversea charges. After tons of research and seeing no other tuner is pushing out that type of gain with my mods, I sold my AP3, and was ready to start.
Ed informed me to download Team Viewer so he could remote into my machine and download all the applications needed to setup the logging parameters and created the file structure for logs and roms. Even if you are not a newb to open source tuning, LET HIM SET IT UP. It will be easier for everyone and if there are any issues, he is perfectly capable of correcting them.
Once all the preliminary stuff was done, he sent me a version zero rom to show me that my car is capable of a lot with stock boost. My jaw dropped. Throttle response was insane, the torque was there, and you can clearly feel that the car enjoyed it much more than the Cobb OTS tune.
As the process continued, you could feel the car run better and better as the days went on. He transformed my car so much, I would rather drive my car to work, Downtown Washington DC, than take the train. I feel like a little kid every time I hit boost now.
With XRT, they could get maps out same day or next day. Ed is very good with being responsive within a few hours and letting you know if you need to check something on your car or not. He is very particular about how he tunes a car and how it is running. Making sure your car is mechanically fine is key to having a smooth and successful tuning process. Overall, he is a skilled and very knowledgeable tuner. He changed my car from a slow non- responsive 2011 LGT into a responsive torque monster that I enjoy driving every single day. Boost comes on smooth, the car moves when I tap the gas and everything on the car feels great. It took about eight to nine revisions before the car got where it needed to be. He is done with my Subaru for now, but he will be doing my GF’s 100% STOCK CVT Crosstrek and I am sure I will see major improvements there! I attached a Dyno sheet along with Ed’s Virtual dyno of the same dyno pulls.
I was referred to XRT by a fellow member (golferdude1087) for a tune for my 5th gen LGT. I contacted Ed and he responded immediately with answers to my questions, helped me get setup with the necessary software, and sent the initial tune. Out of the box, it was a massive awakening for the car. Its the first time this car put that big of a smile on my face and even impressed my friend that drives a tuned 3 series. After a few days of back and forth with logs and tips, we are now on version 3 and it runs great. It pulls hard and smooth throughout the entire range and still gets decent mileage with “spirited” driving. The logger “dyno” numbers say about 275hp/340tq (wheel) compared to the stock 265hp/258tq (crank), a significant increase even if the software isn’t accurate. His tips on things to look for and areas to improve give me confidence that the tune will be safe too. I would definitely recommend an XRT tune to anyone looking for reliable power.

Subject: Low end torque
Low end torque is much improved, to the point that small maneuvers like passing or cornering can be done without getting into boost. Accelerating from low rpm’s is also better, letting you stay in gear when you’d normally have to downshift.
What a great way to start the day!! Now I am officially a part of the XRT Family and wow did I wait too long to make the change. I will do a write to explain in depth but I must say that at stock boost levels (which I was running way higher before) the car is a new machine In Every way!! It feels so great I can’t stop smiling !😬 The car just wants to go! The power is so linear and smooth and are used to have an issue with some choppiness throughout the RPM range which is completely gone now!! Thank you Ed so much for the genius that you put in to every car that you work on the customer support and the knowledge is unsurpassed everyone should be on a tune by Ed I don’t think anyone one who isnt really realizes how much better their car will be because of all the Forst comments from people saying oh when you buy your car/Subaru you need to buy an Cobb, WRONG!!!!It is going to be my goal to change all of that! Have a great day everyone I will update more as soon as I am out of work
Thank you so much Ed!!! You are true genius with tuning!! And also such a great person to work with!! Can’t wait to see what we can do with this car as time goes on!! I have people already calling me for rides so they can see lol.
So I don’t know if everyone knows but I have left Cobb and have moved over to XRT Tuning. It is still the beginning as we are doing a lot of data logs to keep fine tuning and adjusting different parameters of the ecu but I can honestly say that I have never had my car feel this good!! The response of the turbo and the engine used to have quite a delay and would stop making power around 5000rpm. Also I was running 19-20psi. As of right now I am at stock boost levels and I have much better response from the engine and no delay in the drive by wire system and I am also happy to say I am making much more power at way less boost and the car continues to pull and wants to go and keep pulling past redline the power delivery is absolutely incredible and we are nowhere near done tuning it for anyone local who does not believe you are more than welcome to meet up with me and feel it for yourself and see how a really great tune can make a car feel. I am running much safer and not overly rich as the prior pro tune was running. It also got rid of the so called “STi shudder” that people say is common lol. I will continue to update this post along the way so everyone can see what happens and for all the Dyno guys after I am at a point where I want to be I will get a pull done to show the numbers. I highly recommend XRT tuning he is a genius at what he does and ask anyone who has been tuned by Ed and I am sure you will get the same response and his customer support is like none other. I regret not doing this sooner but I Believe everything happens for a reason so the prior moves led me here and I am very fortunate to have someone as knowledgeable and talented tuning my vehicle! Thanks for reading 5th gen fam. If anyone wants to PM me to find out more details feel free.

Well from the research that I did and talking with ALOT of people at all the shows and different forums the tuner that did the pro tune was regarded as One of best tuners around these areas! 😂 He has done a lot of subarus and quite a few 5th gen LGT’s. I am not trying to bash him but after seeing how poorly the car was running and how everything was set I’m positive that everyone should be tuned by you Ed. The way my car has felt from V1 is still better than what he did! Now that we are in a better state knowing how the car is running and the way you have adjusted everything I am driving around with a smile from ear to ear!! I have caught a few people at stop light look at me and probably wonder why a crazy person is behind the wheel but that is because they have never been truly happy behind the wheel of their car , which I can proudly say that I am and I know that things will keep getting better as she learns more. I also want to thank you for the unbelievably great customer service/support that I have gotten and continue to receive. It is so much better than anything I’ve delt with since starting with my car. Thank you very much for being such a great person and a genius at your craft!! I can’t wait to see what’s next!!!!!!!!!
Lol I don’t mind having at least a mini stroke from happiness!! It’s so wild to me that there is still more to come!! It is such a pleasure to work with a tuner as great as you because out here it would be like pulling teeth to make the tuner even give you one revision.
Just a little teaser. Waiting to see the 1/4 mile time. Dbw aggressiveness been crank up a little and so did the boost 4400+. Awaiting logs to see the flow pattern.
Graph shows the TA Protuned Cobbs running more boost vs XRT tuning running a tab low boost in mid range and much lower 4800+. All power is gain by TQ Management, Dual AVCS tuning, reduce fueling and ignition tuning. Again I am waiting on further logs to finalised the tune.
Luis please your last throughts.
This last update again felt amazing
!! The Power delivery is so smooth and so linear it feels as the car just wants to keep going if there wasn’t a redline in place lol. It’s amazing how responsive the car is with the DBW and Turbo response also the way the car sounds is different and more aggressive sounding when getting on it it makes me smile even more LOL To know that there are still things that can be adjusted is wild to me because of how far this has already surpassed any of my expectations and it is light years beyond the tune that I was running prior! Ed you are a true genius and are able to do things with a tune that I have never experienced and I know by all the people you have tuned and how happy everyone is that this is a common occurrence why anyone would not want to go this route is beyond me because from now on I will no longer have any car without being tuned by you! I will update more as time passes thank you again Ed and thank you everyone for following this post stay tuned there is more excitement to follow!
Thank you Ed!!! I was admittedly one of the people’s who get into believing you need a cob if you have a Subaru and did not do enough research beforehand. I am a true believer that the power is in the tuner but it must be an experienced tuner with a great track record like you!! To this day my car has never felt this good and the power be so liniar. I can’t wait to load V8! I will be updating after you and I speak.
P.S. That is another HUGE difference, the customer service and support is dramatically different with you because you care about what the customer is telling you and want the true feedback so that you can see how the car feels to the person. Most tuners just set it how they have been used to setting it on other cars and send it on its way. Thanks again for all your help and being such a great person as well as a truly talented tuner !!! Anyone who wants their car to perform the way it should and better than it ever has needs to be XRT Tuned!!!!!!
