On pd blowers I think 8 or 9 psi is about tops with the stock l99 cam. Much more and you have too much boost at the peak torque and detonation is too hard to avoid without giving up more power than its worth. That's why I went centri. 7 psi peak torque, 13 psi at 6200 rpm redline and all is good.

I think you should invest ID 850's, the fuel rail mod, ZL1 pump, ADM FPCM, and then push 8 or 9 psi. You will love the power once the tune is on and You have plenty of fuel supply.
2011 SS IOM Vert. ECS Vortech 13+ psi, Water/Meth, 2800 stall, LT headers, Drag radials, Drag alignment, Cradle Bushings. Tuned by Ted.
