Like I said, it can happen but there are manny other things that can cause it to. There are was to tell if this was the tuner, how did the cylinder walls and pistons look on kdubs motor, was there signs of detention? Everyone is coming in here like they can tune a car themselves when they should be takin a step back and thinking before they talk. Joey your car blew up and so did stallmers. Is morgan a terrible tuner?, for sure his fault…
