In addition:I've switched to an XRT (Xtreme Racing Tuning) tune and all I can say is WOW!
The car is now updated with both the latest stock FHI/SoA ECM and TCM stock flashes and tuned on top of these.
We're 'only' on the 2nd revision and already making great progress.
Ed has been a pleasure to work it. Extremely knowledgeable, professional, responsive with performance and log results that back it up.
Engine runs great, transmission runs great, no longer constantly tries to upshift to 5 all the time, holds lower gears, responds far far better to throttle input and delivers the torque I'd expect at low and mid-RPM.
StevenC, you're spot on with how the 5EAT can be transformed.
All thanks to Xtreme Racing Tuning. I'm impressed.
First of! Wow! I'm not sure if you've already tweaked the TCM affecting params and table, but WOW.
The 5EAT holds gears, shifts much better. Its a night and day difference.
The engine itself seems much happier, runs better, idles better. And it seems like during the whole log IAM stayed constant at '1'. Which is great!

On my 3rd revision with XRT and the car is responding very well to west_minist's changes!
v0 was already great - great idle, low/mid range torque, great transmission behavior, zero knock.
v1 improved throttle response, made it quick and crisp and added even more low/mid range torque, further timing and AVCS tweaks.
v2 (latest) is the icing on the cake. Rounded out all the changes from v0 and v1.
Smoothest power delivery, pulls great from low RPM all the way to 6.x K RPM
Nearly ideal throttle response and transmission behavior (I can't imagine it getting any better!). The car responds to throttle input like a 2015 WRX in S or S# and the transmission works very similar to it too. Holds gears, downshifts and upshifts very quickly.
More testing this weekend.
Quick update on XRT (Xtreme Racing Tuning) e-tune progress.
We are on the 4th, 5th revision now and the car runs better than ever!
As smooth and linear as she was in stock form with less than 100 miles on the ODO,
but of course far far stronger.
Very crisp, quick throttle response all around
Great low and mid RPM torque and power delivery in any gear
Strong high RPM and WOT pulls (she pulls hard well above 6K RPM)
Butter smooth idle
Drastically better 5EAT behavior (gear selection, holding, engine braking, shifts in auto and manual mode)
Improved sensor readings and ranges (IAM, A/F Learn and Correct, MAF voltage vs g/sec scaling: happy engine, happy ECU)
Further refined engine sound (likely as a result of AVCS, base and max knock additive and cruise timing table changes)
The tune has rounded out all the mechanical mods and even stabilized Bank1 and Bank2 AFRs, especially at idle and under CL driving... exactly where I need and want them to match.
Hats off to Ed for his work! We are almost done I bet, just refining at this point.
