First of all merry Christmas to every one...
Well, im having this issue that no matter what i do, power drops at 5800 rpm, same point that maf pid gets at max 655 g/s(not sure if related).
I cant see throttle closing, almoust no knk but it drops baddly. AR headers and dual 3 inch straight pipe so enough for 608 whp i am making.
Attached files.
Thanks.
