My turbo timer was working perfectly for a while. I installed a SFMU and I have lower idle pressure now. The car idles fine and runs fine. When I turn off the ignition it will almost die then the TT kicks in and idles back up then dies immediately after. Even if I hit the gas it tries REAL HARD to die out. What could be the problem? If it idles w/ the ignition on why won't it idle w/ the TT? tia

i would say it's your idle pressure......if the TT saves it though and works just leave it (assuming your idle pressure is in a good range).

Well when I turn the ignition off it almost dies. Then the TT kicks in and brings it back up to idle speed. As soon as it hits idle speed it dies right back down. So basically it runs for like a second w/ the ignition off. I'm going to raise the pressure when I get off work and see if that helps.
