I posted before about the car going lean or not getting enough spark whenever I hit boost. I replaced coil and it was good to go or was it? Today, I went out for a spin and it started to do the same thing. It just wont go under boost. My vacuum is real low, about 12 but I am getting enough fuel. The car wont let me get past 4psi boost when this is happening but at that 4psi, I am getting 80psi fuel pressure. Idle vacuum is real low like I said about 12 at idle. Whats the problem here? No leaks, ive checked. What else could it be??

do you blow oil all over the place? when i had low vacuum 1 time a big ass chunk of carbon stuck one of the valves opened a little. but the second time i had low vacuum was when i cracked my ring lands. but if that is the case you will blow oil all over the place when you go into boost. lates james

I dont go into boost, the car wont let me without screwing up so I dont do it. I found the problem (the leak), its the damn Cartech FPR. I just sent it to HRC, awaiting the new one.
