Red X = Pure Sex!
I am thinking of getting the Hypertech Power Programmer for my 2000 Xtreme V6 auto, and wondered if its worth the $345 price. I know you can input new wheels sizes for any tires you get, raise the top speed, but does it actually shift harder and accelerate better? I have a K&N Gen 2 intake with Flowmaster exhaust, does this make any difference? Do you get better fuel economy or worse with the HPP? Thanks for any help on this expensive device.
