I have the Sc400 V8 Maf, the turbo XS kit with the T61 turbo. My injectors are stock for now and everything is stock other then the turbo kit, but I have to fix this problem before I start tuning for power. My idle is crappy my cold starts are crappy and if I cruise on the road at a constant speed and dont havce my foot on the gas it feels like a hit a brick wall untill i put my foot back on the gas...
