No color in my spark plugs

Proper meter? Can you increase the Pulse width on the pms? Have you checked the heads and block for straightness?

I would save for a trip to the dyno and tune it there.....there are alot of reasonable dyno's here in central ohio.....or buy a wideband.

I have lowered the boost to 9# till I get this problem fixed.and I am saving up for the dyno.Meter is a pro-m 75 for 42# and supercharged.

Mine are also white (look like they came out of the box). I have many many wide oopen throttle blasts and a dozen or more passes down the track, no problems yet. The car does pop and backfire a bit when I let off the throttle and let it engine brake itself down. I honestly don't know if it is lean pops or unburt fuel in the exhaust igniting. The car smells and feels rich, yet the plugs are bone white in my car also.

Mine also smelled and felt rich but I think it was really lean because when I would run it threw first and secound gear my temp would go up and it would start to cut out at about 5600-5800 rpm,like it was hitting the revlimter witch is set at 6600.
