Turned the boost up to 19psi, Thrasher 100 chip, turn on point 14, pump speed 8, fuel pressure 45 static. Running 65mph in third then wot the car pulled pretty good. Scanmaster showed 1.6 knock and 800. The problem is in the lower gears. It pops, sounds like through the intake, and starts bucking when the alky kicks on! Can't get a reading on the Scanmaster because I get out of it really quick. What's happening? By the way I'm running 70% isopropyl. Any help would be greatly appreciated. Thanks, R.B.
