2005 gxp tune questions i have a 2005 grand prix gxp and i would like a hand held tuner... ive been reading great things about the lew tune and would like one for my car as well i was just wondering what i will need to be able to use his tune and what tuner will i need?
the diablo handheld tuners will not work on the '05.....I found out the hard way. I contacted them prior to buying and was told that they had gotten it to work on the '05 GXPs.....I paid for a new tuner, hooked it up and it was incompatible with my '05...ended up having to lose much $ selling the tuner as "used"
