Hey guys...
i would like some help regarding my car.
skyline r34 gt-t running a power fc, hks 2535, bosch fuel pump, splitfire coilpacks, 600cc injectors.
I'm not sure if the tune is out, but every time i try to accelerate over 3k rpm. it struggles and the exhaust pops a lot, makes no power at all.
I've asked a few people and some have said AFM, boost leak, dirty injectors. I've swapped the AFM meter over so that's out of the equation.
Any suggestions guys?
Thanks in advance
