I tried doing a search but had no luck. I have a 03 coupe that im in the process of putting a turbonetics kit on and I was wondering how does the fuel pressure know to raise with boost when theres no reference for it , I will be using a Utec with it , any help would be great thanks, John

 

ussually kits have a FMU=fuel managment unit. most of them are boost dependent. more boost=more fuel
