[QUOTE="LSX_Terminator, post: 15478255, member: 136775"] I have had the car for a few months now and the dealer installed the 670hp kit with the very weak Roush tune. I like driving it but the car feels like it has alot left on the table. Are the companies like VMP, Lund, ect... able to overwrite the cheap Roush voucher tune? Anyone seen better number from a custom tune with this kit? [/QUOTE]
