Anyone use the "Flashpaq" tuner to get more power out of their 6.0 GM, and does it work? I called them and they claim you will get 30 more HP using their tuner in tow mode. I was just wondering if anyone else has used one and if it helps at all... Thanks
You'll get more answers if you post in the Tow Vehicle forum.
