I have an 09 corvette and I am thinking of having it programmed which one would be best. Letting a tuner do it or buy a hand held programmer

Whichever doesn't affect the warranty.

Probably both will affect the warranty. Want some more HP

Is there anything done to the car? If not you would probable get more out of a tune if you did at least a basic intake/catback exhaust.

And unless you have experience tuning you will probable get more out of a professional tuner. But both handheld and taking it to a tuner are effective as long as you know what your doing

They all screw the warranty.
On my dads 2010 Camaro SS He had ted genety do a custom tune and it was a whole new car after he got done. You tell him the mods you have done to your car and he makes a tune that corresponds with the mods. If you get a tune i would talk with him. It's not cheap but it's worth it.

Might as well take the 400 bucks and throw it out the window then spend it on a handheld...get yourself and cai and catback and bring it to a good tuner
