So I have been doing some research on getting a custom programming done on my Ennvoy. Looking for a little more pep and better gas millage....

Looks like the Hardware required to re-flash/program the ECM is fairly expensive for somthing im only going to really use once. I can justify 500$ for the software hardware for it.

Does anyone have a programmer, And how much beer would it take to get my Envoy re-flashed ?
