fuel to boost ratio

[2.2 Turbo]

does anybody know how much fuel to add for every pound of boost, i forgot thanks

[xrattiracer]

enough to keep the mixture at 12.6:1.

Typically boost reference fuel pressure regulators are set up 1:1. So 1 lb of pressure per one pound of boost

Thanks that's what I wanted to know.

and technically thats not adding fuel, its just keeping it the same. the idea is to maintain a static fuel pressure across the injectors.

exactly.

what you can to do is run a fuel pressure gauge off your fuel rail and mount that gauge where it can be seen while driving, for example you can duct tape it temporarily to the outside of the windshield...then take it out for a test drive and make sure your fuel pressure goes up 1 psi for every 1 psi of boost.

for optimum tuning , power, and reliability you also should verify the air/fuel mixture at maximum boost, 11.0-12.5 is a good range at full throttle.
