I'm running a 2.5 with similar head work but 8:1 and 92 for fuel picking up boost at 4k and it made more power till I cut it off st 8k.

But that aside good work making that bay clean, also what fenders are those?
Turbo should be okay because its new with 4 inch inlet anti-surge. and i did check it before i get it fitted on.

some further questions for all your guys. The answers will be appreciated.
What is the possible problem to cause late peak boost and less power apart from hardware failure.
Some reference datas:
afr 10.6-10.8
IDC (dw1000cc) 91%
2.2 kit
gtx3076 22-23 psi
ignition 13-14 degree
Bad fuel in my city

Thats what I did during the tune to make knock free. So weired.
