Re: AHH My 2 is finally awake!!!!
Contact Corvettes of Westchester in Ossining NY. Chuck does mail order tunes on C6's but I am not sure if he can with Hummers. Now that I added a cat back exhaust I will go for a re-tune to further enhance my driving experience... The in shop tune is $500 I believe but I had the oil changed and at his recommendation added a 160 stat. Truck runs cool as can be. Well it is winter but the needle reads so much lower! His mail tunes are a little cheaper I believe.Throttle response is awesome. Shifts are now longer in between gears and harder too and overall feels great!!
