i have apr software on my stage2+. how much horsepower can my stock fuel system support? does anyone know? and if intake temps dropped dramatically at the maf would the ecu be able to compensate some more fuel and timing? i guess im wondering if my stck fuel system can support more power than what my car is making now and if so how much

 

well as far as i know your stock fuel system is okay...the only time i've ever read about someone needing to upgrade their fuel system is when they go full stage 3 so unless you're going to do that then i'd say you're fine!

 

I've seen the stock fuel system doing well on 305 whp Stage 3- setups, which is close to 400 chp. I don't know if that helps give a perspective.
