Not to go too far off topic here... My buddy and I have been smack talking and this badass Tahoe talk is kind of making me wonder. He's got a 2005 chevy 2500hd 6.0- intercooler, headers, tune... Maybe a few other things. Says he runs a 14.9 1/4. I think I'm right there with him w the Buick and listed sig mods. Thoughts? We've both been way too busy to get to the track.
