#8814, "boostin"




          

I finally got time to install my profec b boost controller and its awesome. easy to figure out and all that good stuff that makes greddy great. Anyways, I got the boost set to 10psi but when I hit 10psi at like 5k rpms my engine starts to bog down. Kinda like its not getting enough gas but my fuel pressure is 120psi at 10psi. I dont know what to do.

I just bought a different FPR in hopes to fix the problems that the hahn racecraft one has. If it doesnt fix my fuel problems then I know its the injecters not letting the gas through but stock injecters should beable to handle 10psi right?? maybe I should drop it to 9psi?

On a stock bottom end I wouldn't run more than 8psi unless you have race gas. It just depends on how long you want your engine to last.

I would think the engine bogging down would be from too much fuel, not too little. The car should feel faster as you lean out in higher RPMs.

The stupid fuel pressure regulator is all screwed up..I think you may be right on the pressure being too high because I am just now starting to get a lot of backfires. How the hell can I lean it down??? It only happens at like 5-6k rpms.

SAFC is the best way to lean things out in the higher RPMS.

THe problem with a raising rate FPR is that it is only adjustable one way. an SAFC lets you control your fuel curves throughout the RPM range.

I use the S-AFC and everything but there is a problem. The damn FPR is always changing what pressure I get. So no matter what the AFC is set at it is always wrong because of the FPR. I cant wait til I get my new one so I dont have to worry.
