Man, I seriously need to get a retune and dyno again. My listed dyno is only through 6.4k rpm and with a hell'a bad exhaust leak. I did have a very flat torque curve though, 221 @ peak and 206 @ 6.4k.
Should be better the next time thanks to ^^^ the changes above. I'll actually be able to run up to ~7k without my AFR going all wonky like it does with the Stage 2 42# injectors.
I'm also not running the maximum timing I can without knock, since while doing the last tOoN we hit a point where I actually started dropping in power.
I posted my SAE corrected numbers. I was only 236whp on the Stage 2 tune and 251whp after the custom tOoN. Didn't gain any wheel torque, but my peak moved from ~4.45k on the Stage 2 to ~4.3k on the custom tOoN and was a lot flater overall. Was over 12ft/lbs higher at 6.4k (highest that the stage 2 injectors wanna stay stable till, went all wonky higher).
I, H, DP, E, T (need a new one), DU, 55s (not installed due to lack of tOoN), 2.9", HE
