I'm sorry if this question has been done to the death. I've been searching for a while and have found so many conflicting opinions with no actual dyno charts to prove anything. I've asked engine builders and they couldn't give me a definitive answer...
So here it is (as the thread is titled):
Gti6 intake manifold (with gti6 throttle body) on an S16 XU10 - what are the gains??

, Some of these are actually copied from people here and they aren´t really conclusive either. As it is now i have a well functioning ACAV system on mine, and as soon as "mr swampy S16" gets on the move and sends me the decat i´ll start sorting with the exhaust to.
