Ya was seeing 8lbs. then over the weekend I put my superchip programmer back on because it shifts alot better with it. So now it doesn't shift untill 5500rpm and 10psi at wot. I know don't use a programmer with a supercharger, but I don't hear any pinging. The only problem I'm having is ses light P0300, but I've been getting that at full boost sence I but the s/c on. Ordered direct fit MSD 8.5mm wires tonight, maybe it'll fix that.
