OK short and to the point on 10psi I made 318hp and 220tq on 15 to 18psi I only made 338hp and 255tq. A/F was about 12 to 12.5 it got a little higher on the height boost runs almost to 13 because of the DSM450 and it creeping to 18psi 750 are on the way.

My question is shouldn't I be making a little more then 20hp and 35tq on top of the 318 and 220 with 15psi?
