I converted to an LS3 setup and need help running down a problem. Car runs fine at part throttle below 3600, as soon as you get in it it breaks up and won't pull (does seem to clean up a bit around 5k). I swapped coil packs, new plug wires, new plugs, got rid of the crappy ev1 adapters for the racetronix adapters and chased every wire I could possibly think of. All grounds seem good and no broken wires. Maybe a bad cam sensor? It only runs bad under load. Fuel pressure is 58 lbs at idle and under load. MAF reads correctly according to PatG. I don't know what else to try.
