Tuners?
I have heard a lot of things about some of the tunners that are out. Like the Hypertech. I have a 99 LS1 Trans Am, are these things worth getting? Do they really work? What do they do? Any info would be great.
Thanks
Do not expect to see any kind of noticeable power gain that even warrants the time to download the tune though. If you want power, get a custom dyno tune.
