Hi all, im still fairly new so please bear with me ...... I've got an gtst R33 which has the following to be fitted in the next few weeks, greddy e-manage(blue), greddy type m fmin, apexi avc-r to be set @ 0.9 bar. She's already has blitz down pipe, hks cat back, apexi power intake, hks spark plugs and a turbosmart supersonic bov. My question is will i need to fit an uprated fuel pump and also a fuel regulator (no idea what one is!) which i've read about on the forum, or will it be ok if i fit a walbro would i still need a new regulator?? any help would be appreciated, thanks guys!
