I would like to get a Superchips for my 02 1500 HD with a 6.0. Does anyone out there have one and if so do you recommend this product. Reason for considering this is I went from a 245/75 R16 size tire to a 265/75 R16 and it changed how this truck responds.

 

I had a superchips flashpaq on my 05 2500hd and it really woke my 6.0 up at first. It ran like a bat outta hell for awhile and then it kinda became not so impressive. I ran it on performace mode for about 6 months and it started causin my tranny to have shifting issues cruisin down the highway. I don't know if I adjusted it too much or what, but I'd never buy another one.

 

Do not waste your money on a box tune. Look into a custom tune. I have read good things about Black Bear.
