I just wanted to plug an amazing Corvette mechanic. When I picked up my '05 V I really was nto sure where to start the mods. I hooked up with Chuck from Corvette's Of Westchester as he had been a huge help with my vette. He immediately told me of the major success he has had tuning most GM vehicles with a program he purchased. He has been able to get some serious power out of the car bone stock for less what it would cost to change the exhaust. I gave him my brand new V with probably 400 miles on it at the time. All I can say is within a few minutes of waiting with him as he played with some of the options, the car was completely different! The factory tuned the car so far down that when I got behind the wheel it was an incredible difference. Recently he has upgraded to a different software package and has tweaked the V even further. I added a borla exhaust and an intake but neither coems close to the bang per buck he gave me with the computer tune. I highly recomend anyone that can make a drive to Westchester County to call him. He is called the Corvette Doctor and he will show you how he got that name! Don't waste allot of money adding parts to the car until you get the software enhanced first! It will give you a huge edge!
