In a perfect word, you would have 27% more power. Your crank HP would go from 130 to 165. If you have a crappy intercooler, or don't have it tuned properly, that value drops.
((Boost+14.7)/14.7)-1=%HP Gain
4psi=27% Gain
7psi=48% Gain
10psi=68% Gain
14psi=95% Gain
Just think about it. Atmospheric pressure is 14.7psi. If you double the pressure, you double the power.
