Dood. You should just keep reading more and find out everything you can about the fuel management and turbos on our cars. I'm not trying to be an ass or anything cause I was once where you are right now. Wanna boost the car but actually don't really know much about it at all. There will be 20 comments from peeps here saying search, search and search cause they are right.

If you don't know what an AFC is "ACTUALLY" doing (modifying signals sent to the ecu) you'd realize it doesn't do much as far as Tuning your car. I don't care what you buddies buddy or your friken mechanic says. They don't know shit. You need to understand what a MAP sensor is and an o2 sensor and what a rising rate FP regulator is. You need to know that by raising fuel pressure your stock injectors will be at like 90 - 100% duty at WOT. Thats no good. That means bye bye motor. You just need to know a few more things.

Absorb the knowledge 2GNT has to offer.
