Hi im just interested how rich your cars are running, i got an F20C with revhard turbo kit, 550 cc injectors, 3-inch dp + inline pro exhaust (no cat), aem ems, running 7 psi on stock compression 11.0, what A/F target should i have to go safe ? 12.5 ?
A friend of my told me not over 12 because of my high compression, but i think it seems a bit rich ?
I´m looking for ~300 whp.

 

In full boost I'm around 11.8.

 

^ Mine is about the same.

 

dyno will tell the story. but 11.5-12.0 is typical for FI on this car.

 

usually 11.5-11.8 on the safe side

 

right at 12 flat
