2007 GXP in Boise

[BoiseGXP]

Ive had the car for about a month and a half. Car has 136000 miles and was a salesmans lot car. I have drained and filled w filter the trans twice in the first month...buttbrown fluid. Third time I added a transgo shift kit and a tru-cool cooler. Oil change and radiator flush the first week. Diablo tuner came in the mail last week, 91 octane and dod off tune. Car seems to run like a champ.

Sorry, I wouldn't dare, I might make a mistake or the car just won't meet your expectations.
