Hey guys have had my R33 GTS-T modified and is running rough as guts, i have been told that it is the AFM. would anyone know where i could get a good AFM in Australia that would go in.

Hi guys, Just new to the forum's and just figuring things out. I have had my R33 GTS-T for about 3 months, i have just put these modifications in, Garrett GT3071R Greddy Air Plenum Larger throttle body New TPS ( throttle positioning sensor) New coil pack Spark plugs Apexi PFC HKS Exhaust manifold Front Mount intercooler 3.5" Turbo back Exhaust We are just about to tune and car sounds like it has a couple of lumpy cams, i have read a little about the airflow meter, unit looks clean but. if anyone has a resolution cheers Luke
