hi guys....

i ve a stock engine with full 3'' exhaust, trust pulley, power fc, knight sport turbos.... i ve a sard fuel press regulator in secondary injector...what is the best pressure setting? and the stock?

thx

 

I set for 40psi as a base pressure with the vaccume line disconnected. Then recontect the line and make sure it rises when you open the throttle.

The stock fpr is 36-38 psi just for your peace of mind.

Hope this helps.
