thats a pretty similar setup to what i have on my 04 VIII, and on pump gas, i ran consistent 12.8's at 108ish. switched to race gas (110oct), turned up the boost a little, ran a little more timing and went 11.80 at 120.
keep at it, you'll get better, im a pretty crappy driver myself, but i just run drag for turds n smiles, and a good solid number that other people can understand when they ask "how fast is your car?"
most importantly, just have fun with it. you're going 12's on a basically stock car.
