Class canceled, so i went to tinkering, im pulling 19 psi vacuum at idle and about 7 pounds boost tearing down my driveway. It still floods itself whenever i cut it off though, and it sounds like it has a bad exhaust leak between the turbo and engine, with the fcd and manual boost control, i think it should be pushing more boost but is losing pressure from the exhaust leak. It was running like crap, today i couldnt even get it to stay running, turns out that the hose clamp on the intake at the turbo was lose it was giving the car a funky reading for the afm, the numbers above are after i fixed that. Now i have rough idle, and flooding, its always had the rough idle so thats not a new issue. so the problems are going away as i tinker with you guys help. When i got it, it was so bad the owner flat out told me the engine was blown. That was just a busted heater core hose causing it to lose coolant and overheat. Im thinking the injectors are bad, if i pull the fuse and crank for a while then put it back, it starts.

So does any of that sound right or plausible???
