how big of tires did you go? I put 285s on mine and didn't even notice a difference....of course I have always had a programmer on my truck, but I don't always run the programmers.
I am, but not big stacking....I still have a stock tranny, so I don't want to mess it up too soon. Most of the time, I only run one on the programmers with a mild tune...Usually nothing over about 80 hp.also just another question. Are some of you stacking a tune on your computers with a programmer like an Edge?
