I have a 28' K-Z Jag that I pull with my 5.4. Dry weight on it is somewhere around 8500 lbs. With the canned 87 tow tune, a cai, and until recently just a cat back exhaust my truck would pull it uphill at 75 w/out really kicking down at all. But I just ordered custom tunes do to the fact that although it will do it, is it that good for the motor/drive line?
