He also set the timing retard at 0.75 deg/pound boost, and showed me that at 8lbs it was still a bit conservative, so I stayed with it.
The thing absolutely rips!!
It drives perfectly like a turbo car should. I'm gonna get a datalogging cable made up, and then tune it a bit more when I can, but it's almost as if it drives perfect. I got a 3500 rpm launch control, and a shift light (check Engine) at 7500, fuel cut 8119.
With the lower ignition setting the car has alot of torque down low, it definitely helped.

Why so low for vtec cross over?
Generally the power curve is better when you raise the cross-over, lowering it usually creates a dip in the power curve.
