Hey guys. I just wanted to check this setup. I'm building a street ported S4 TII. The setup will have a straight through exhaust and the TID mod. My question is about fuel. plans are



720cc secondaries- mandatory for Rtek

walbro 255lbh fuel pump

hks super afr piggy back



will these modifications support the gains I'm planning? I have already ported the wastegate in anticipation of more boost. Should I get an adjustable FPR? Is it even necessary?

stock turbo w/ ported wastegate. I need to operate within the confines of the stock turbo right now. However, I would like to extract as much Horse power as possible while maintaining a good margin for safety. Im hoping to get anywhere between 240 - 300 hp.

for stock turbo, 720cc secondaries and 255 fuel pump should be more than enough, and leaves room for an upgraded turbo...,
