I'm having a strange issue tuning a 2008 Evo X GSR.
I've tuned a couple of my friends Evo's as well as my personal Evo with no issues prior. However this 2008 is consistently applying fuel trims during WOT even with the fix in Closed Loop LT Trim Control. The vehicle is fairly stock, on stock injectors and fuel pump. Has a test pipe and catback exhaust as well and an ETS intake. My trims at idle are within +- 2% and my cruise trims are within 3-4%. If I reset the fuel trims the car will hit 11.5 AFR at WOT until the cruise trims begin to populate then it leans itself out to 12.0.
Not sure what the issue may be, have tried ROM ID: 52680022 as well as the Tephra v3 variant for the 2008 Evo. Any tips appreciated!

Gotcha, looks like I did replace the correct values with stock values at some point when converting to tephra. The map I pulled on the car originally had:
18.75
12.5
31.25
25
Most likely my personal Evo cruise trims were closer to 0 and I was not applying noticeably corrections during my WOT testing.
