How much nitrous have you sprayed through the intake
Had to have it super super rich (10.0 and richer), when I leaned it out to 11.0 where it should be I burnt a couple plugs and beat up the pistons. Even with it rich the car ******* moved, but I picked up 3 mph in the 1/8th before the plugs burnt when I leaned it to where it should be, which is one of the reasons I went away from the stock style intakes and put a gmpp carb style intake on the car for the new setup, we'll see how that does on a 400 when I get the spray bars plumbed into it.
