Hey guys I need some help wen I floor my truck and I'm goin at high rpms with the windows up I could hear on driver side craklin noise from the engine...any info will help thanx..
its a bad tune. need to talk to your tuner and stay out of WOT till you get it worked out. it mean that the upward piston is being met with the downward force of the combustion to early. its like hitting the piston with a ball peen hammer. very bad.
