My car has been tuned for my mods and has alwasy run great. Recetly it was broken into, and somone stole my ebc. I ran the car without a boost controller for 3 weeks conservitively and never boosted over 6 pss (highest it would boost). Now that I have gotten another controller and set it at my preivious settings, the car is throwing black smoke more so than it ever did before. The boost is the same, but the gap of having no boost may have messed with the car. I'm going to get new spark plugs, and reset my ecu. I just moved it in the parking lot, and you can smell it (fuel-ish smell). I think iI probably fouled the plugs while it was only running 6 psi. I had also noticed a slight stuttering while it pulled through the rpms at wot. Any other things that might possibly be contributing to this problem?

Thanks,
Ben
