wow i just got my 06 sut back from the supercharger shop and you guys said they were fun but didnt say how much fun. my question is i have the stock program from magnuson. i dont realy like the shift firmness did you guys go and change with the stock tuner or did you get a new program? also is a softer **** better for the tranny life(im guessin yes??) or would the firm have a big difference? thanks.
