I have a friend with a 03 vert that is detonating at wot. He has had several different tunes put in it but nothing helps. He replaced the fuel pumps and the fuel filter yesterday and still the same. The car has a built bottom end, stage 4 steig ported eaton, 60 lb injectors, kenne bell boost a pump, and the car has been dyno tuned, also has after market maf...any ideas or suggestions? Car seems like its leaning out to me but we had the tuner put a "fat" tune in it and still the same thing..
THANKS IN ADVANCE!
