I paid a tuner jan 28th from this forum to get my truck tuned after I did a cam install, I had it in decent shape with no idle dip when stopping. I wanted to get it tuned properly as i felt it was lacking power.. the guy screwed my tune up, the truck will almost stall every time coming to a stop at op temps. I had it in better shape than he did and I didnt have a clue then. I love waisting money on tuners.. I am now ignored after he realized he cannot fix it.. #MASTUNED......... WATCH WHO YOU USE...
