So black bear performance is coming near my area may 5-7. I must have read about 10 threads on the tuning and decided it's well worth the money. Today I should be getting the money for my fender flares so that I can ship them tomorrow. With that money I will put down the $80 deposit. Hopefully they still have a spot open on Wednesday but I think they still do. All the reading about the tune has me really excited and what I look forward to the most is the sport mode since I tow nothing. I do need an opinion from a few who have gotten the tune, is there a big difference between 89 and 93 octane tunes that would justify spending $.30 more per gallon?

Just got mine tuned this past weekend. I had it tuned for 87-89 octane and E-85 since mine is a flex fuel vehicle. For a DD, I didn't see that going with the 93 octane tune would have added much, other than a headache because not all gas stations near us have 93 octane.

I have an Autocal and am able to switch between 87-89 and 93 octane tunes. I've tried the 93 tune and didn't see a difference in either power or mileage and I ran 3 tanks through it on the 93 tune. I have the 6.0 motor. I switched back to the 87-89 tune. If I had to choose one I'd go with the 87-89 tune.

Well, I didn't do it to my NBS, but I did it to a NBS in the junk yard:

Pulled the radio tub, and the trim piece to retrofit my 2000 Yukon XL with a DD radio:


I have some dremeling in my future...

93 octane is all over the place around here, but it's about $.45 more per gallon so idk if it'd be worth it

Ok I'll go with the 87-89, 93 is everywhere near me but it's almost $.50 more a gallon
