When I took my car to the dyno it read 404 rwhp at 13 lbs boost (bad right?), and that was with my stage build but I had stock headers, 3" DP, and a PT-70 journal. I know my tune wasn't the best and I'm thinking my air flow was messed up due to the stock headers and small DP. Plus I had 19" rims on it and people have told me since then that u shouldn't tune on the track or the dyno on rims and street tires.
