I only suggested a step retard because it will improve your low boost performance.
Ok,
I yesterday, I got my DSM 450cc injectors, the resistor box, and the ECU reprogrammed for the bigger injectors.
I had him set VTEC at 4800, and he gave me a little more fuel than on his setup, throughout the band.
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.
