Believe it or not, in addition to my two custom tunes, I also own a DiabloSport handheld tuner I used until I bought my custom tunes. Kinda gave up on it since it's canned tune caused UNREAL spark knock on my truck . . .
Yeah were almost done with it finally!! Would have been done awhile ago but my CAI kept giving me problems. He's done an amazing job IMO. Can't wait till DS gets TCM straightened out. Should be about 2months then we can unlock my trans. I am hoping your knock sensors are causing ur bad mileage.

I'm getting 14-15 city and 20+ on freeway depending on lead foot.

Let me know when you have done a few so you don't blow up my truck lol.'
I'd be interested in a good tune if it could beat the one i have.

Haha, yeah, he's a busy guy. But if you're in Bellaire, he's right around the corner from you and one of the best there is IMHO. Took my truck from not being able to squeek the tires at all, to laying stripes all the way down the block and a mid 4 second 0-60.

According to his sig he's boosted with supporting mods, so I'm going to guess that was post-supercharger; I really can't see a Tahoe running 4.5 seconds to 60 anywhere near stock.
