First off, no I do not have a scanmaster yet. I bought the car not running about 6 months ago, and had to build the motor. I just got it back up and running yesterday. The chip says on the bottom 86-87 strt lthl. So part throttle is really nice, drives around great. But when it starts building boost, it does not start pulling until it gets past 6 psi. No black smoke or sputtering, just not doing like it should until the boost gets over that "hump".
