ok, i have a stroked gsr motor sleeved and built yada yada yada......b16 head gsr cams and a 62-1 turbo, the car just feels like it stops pulling a 7,200rpms, the needle keeps moving but slowly and it dosent feel like its pulling at all, it has about 22-24 total degrrees of timing up there and i think the air fuel are dropping itno the 10.0's. if its not the air fuel what could it please. GURUS HELP
