Anyone know of any good affordable programmers for the gtp?:confused:

there are none.

They have a stage 1 and a stage 2 with a 10-15 HP increase.

thats stuff is garbage.....do u have one?

I dont have one but I havent heard many bad things about them but I know there are a few businesses out there where you can send them your stock ecu and they will replace the insides or reprogram them to a better setting I have a shop in my town that specializes in this stuff they do good work. I think they hook up your car to a laptop and basically tweek with it until they get a higher HP reading and somehow are able to save it to your ecu. The equipment they have is basically the same as what other companies have they just dont bulk sell it. I can look them up and see if they are able to do anything with the g6 because I know there specialty is camaros and corvettes.
