I'm helping out a friend who is working with a budget and wanted to get a hand held tuner for his 2002 C5. He was asking what brands/makes are out there for programmers? Any suggestions? Any sort of info you can give would be appreciated.

Your better off getting a custom tune at a shop.

If you have your heart set on a hand held try out the Diablo Prediator, there are a few other companies that make hand helds :confused: I will need to re post when I think of them.

I agree handhelds are not the best option, howeber if yo have an Auto they can be useful in changing shift points and such...

The Diablo is supposed to be the best one, but for almost $400.00 you can get a real tune...
