Is there anyone in SE Pa. Pottstown area that can do efi live tuning ? Just bought a lly was told it is in perfect shape. On the way home it thru a p0299 underboost. It has egr delete,supposedly tined for non egr, but as you'll read I don't trust this guy at all. By the time I got home from Maryland with it, it was knocking and water was pumping out. Blown head gasket, removed heads and #8 blown from cyl to water port... Replaced gaskets and the # 4 injector that was causing the knock. Runs great until about 1/2 to 3/4 throttle falls flat p0299 please help if you can son needs the truck for Monday to tow his boat to Maryland.
