I just finish rebuilding my engine. forge piston and those other crap. When I first take it out for a drive a couple of days it was fine the egt read out to be about 1400f with my turbo boosting at 6psi and the same at 10psi. But now I dont know wht is wrong with it I am not even boosting just normal driving close to 0psi or 1psi and the tempature on the egt reads 1450-1600 can't even drive past 40-55mph with out the temp reaching 1600f. Wht is wrong with this. I have a/f gauge and it reads fine swing back and forth and also i have the digital one stays around .8 to .9 Also I have the S-AFC II with 30lbs injectors. I even try running the injectors at 0% correction and still same problem. It was just weird that it ran fine the first couple of days. Any help is appreciated

I am using aeromotive fuel pressure regulator is that useless like the craptech? What pressure should it read at idling. I know it is 1:1 ratio is that too low. My idling fuel pressure is 45. I just changed the o2 sensor too, still the same. Also another problem is when I floor the car it goes to lean but when I step off the pedal just a little bit it goes to rich then back to lean. When it goes to lean I notice the pwer drop then goes back up when rich. What the hell is wrong with it. Anyone from around the New England are know a place where I can go to have it tune. I know there's one in connecticut but forgot where.

Yep. The Aeromotive 1:1 is a very nice regulator, but I wouldn't use it unless you had about 550 cc/min+ avaiable at each rail.
Good applications for a 1:1 -Standalone fuel manangement with 550 cc/min+ at each rail -8 injectors -eManange...? -Normally asperated (if you felt inclined to change your fuel pressure)
