OK we are close this one was good!
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!!!!
By the way The AVO turbo kit and the raptor supercharger kits are not available for the 2015+, due to no tuning or fuel pump solutions
Thanks to XRT Ed, I have been given the confidence to move forward with the project. I live by multiple Subaru tuners, and was turned down by all of them. Ed said he was up to the challenge, and I like working with people that have a can do attitude
Now the car is running great. I have made some decent pulls to collect data for ED. He is doing an outstanding job!!! This is the first time anyone has tuned a 15+ NA for turbo and there are a lot of hurdles to overcome. ED is knocking it out of the park. Every time he sends me a ROM it gets better and better. His CVT tune is awesome, makes it feel like a sports car not a grocery getter.

Well I’m going with XRT as far as the tuning goes. His customer support and reviews of his tunes are very good.
XRT has you logging constantly to give you a custom tune for whatever mods you might have installed. Is it a little pricey. Yes but the product along with his customer support is AWESOME!

Just a little update on the tuning I’m receiving from XRT.
As of now I installed the updated ROM he sent me (haven’t driven it yet) but I can say that the prior one was AWESOME! Small issues from when I open it up from a stand still but when I need passing power it’s there!
Tranny behavior is near perfect! And besides all of this he’s their with better than excellent customer support!
Ed, all I can say is WOW! This latest tune v0c3 is by far the best you’ve done! Great power off the line & great power for passing. The rpm’s while cruising 70 or 75mph are great for mpg!
I’m not looking for WRX power btw. I want the best of both for the motor I have and it’s almost there! GREAT JOB!
With the current mods and now fuel review, the car is running very lean.
