I am looking to install a Gforce Chip on my 2003 H2 Hummer, but cannot disconnect the plug. Has anyone ever done this before ? If so what wires do i connect to ( what colors ) i have a 5 wire plug.
ALso anyone with any other gas savings or horsepower ideas let me know.
I have a 2003 H2 With 106,000 with a K&N air system and a turbo flow exh. Right now i average about 10 miles to the gallon.
Any other ideas let me know.


Thank's
Brucet
