Default loosing power on spray

ok i ran 12.09 n/a i was runing a autolite heat range#6 plug and 38 timing, i switched to a #5 plug and went to 28 degrees of timing on a 150 shot and ran 11.teens, i went to a 180 shot with the same timing and ran 10.92@128, pulled down to 26 degrees and went to a 210 shot and it spun and kinda fell over in high gear and ran 10.96@124, and i tried again and it busted up and wouldnt really make power and i thought the carb had a bad neetle and seat in the rear so i changed carbs. i put the 250 pills in and it reved great and clean on the purge and as soon as i hit the spray it and spuittered and seemed not to make good power, i didnt run it out. i hold 6psi of C16 fuel pressure on the nitrous fuel regulator. and i run 100 octane through the carb and fuel flow looks fine there too. i looked at the plugs and they seem to look new on the tip and nice tan towards the bottom(after a trip down the return road) and the blueish color is exactly in the bend of the strap. they have very small brown speckles on the plug that is all that i see??? does anyone have any idea what the problem is?? maybe plugs are too hot????that is what i think. they are gapped@.035 and i have msd coil and box......o yeah i was runing 950-1100 ish bottle pressure
