[Dcarver]

thanks for the info! I never thought to check the 65 mods page because I didn't think anything would apply to my tahoe, but I think I'm going to try the side mirror delete, grill block, and possible underbelly pan (if I can find some large cardboard to do so). I've already done some weight reduction by removing the spare, jack, and just general crap that has no reason to be in there lol.
I guess I hold off on the scanguage. I think i'm going to go for the bluetooth OBD2 module that works with the torque app for my phone. Its only $20 so that doesn't seem like too much of a waste to me.
