You dont get a certain amount of hp per boost. Higher boost doesnt always mean more horsepower. If you look on the dynos on their page and dynos of members on this site, those numbers are high for the little amount of mods you have. Im sure your car is close to that in hp I think that whoever was running the dyno manipulated it so everyone reads higher. This way you might go back to them. Either way enjoy the power. Im sure its a blast to drive.
