Hey guys,

Any suggestions on what kind of progammer/chip to get for my 2001 C5. Basically has new exhaust & cool air intake.

Also, thinking about changing out the coil/plug wires. Any favorites? Which ones to stay away from?

Thanks guys.

 

I would not buy either. You can buy software to load on your computer and enter your own through the obdII port on the car. STUDY UP FIRST !!! Once you make changes they may not be to your liking. With these pieces of software you can do much more that just reprogram for horse power or shift point changes. Just remember they can be dangerous if you are not careful. With software I changed my fans to come on 5 degrees earlier for summer cooling and turned off the dreaded skip shift light.
