wow! matt is just a well known dude......but anyway. RR hooked you up! u can still get a little more basic than what matt is recommending. he just wanted the engine to be safe as possible. HP increase relies on your tuning. a rule of thumb is that: 1 psi of boost is equal to 10 plus/minus 2 HP. so, a 7 psi boost can give you around 50-70 hp gain.......80hp if u get lucky and get the best combination
