Just be sure to not use speedtuningusa for your tune. My SRT lost torque and horsepower after the remote tune. Not much, but I was paying for a significant gain. I got the EUROCHARGEDtune on site at Huston and it was significantly better than before the speedtuneusa remotre. speed tune would not offer any refund and I did not wnt them to play arround with my tune after eurocharged had made a lage improvement.
