Hi, I have a 01 lightning with a stock motor and heads, KB 2.3, jlp plenum, jlp cai, diablo tuner, diablo mafia, accufab sbtb, 60# injectors, 255 pumps, denso iridum plugs, long tube headers no cats, and probally some stuff im forgetting. Now heres the problem about a year ago I did all the upgrades and had the truck tuned at a very know tuner(dont want to mention names) 456rwhp 511rwtrq the truck ran great for about a week and a half and then started missing a little and then progressed to get very bad. So I checked the spark plugs out and they looked ok but not great for new plugs so I changed the coil packs to motoblues. Truck ran great again. About a 2 weeks later started missing again but to make a long story short I have gone through 4 sets of coil packs and plugs in year. I took the truck back to the tuner about 6 months ago and he said it was a corupted tune. So new tune coil packs and plugs truck ran good for two weeks. Exhaust also smells very rich. Does anyone know what the problem could be? The last year has been hell trying to get this thing running good. My tuner is kind of far and isn't that helpful. And when I change the cops and plugs now it dosnt feel as strong so please help.
