You had AFM taken out? You can't have AFM taken out of one mode and not the other unfortunately. We will definitely work with you on any tweeks you are requesting. Are you using 87 octane?
BlackBear tuned!

Yes, I had the AFM disabled. I was told that I wouldn't lose much, and the tune would more than make up for it. I'm thinking that maybe I should enable it again. Just to keep the wife happy. I know it doesn't effect the performance. How would I go about getting an update? Would I have to buy a new ECM then send you mine? Mainly I'm looking at how much extra will it be. Just let me know! I will keep you updated! Thanks a bunch!!!!
Updates are free, you just have to put down a core deposit, which is refunded when you send your stocker back out to us.
FWIW, the mpg on my 99 tahoe hasn't went up either, if anything it has decreased a little. Kind of disappointing because I too was hoping to see a MPG gain. I'm not gonna lie though, im gonna be getting all my Chevy's BB tuned.

i dont believe i had all the afm taken out i just think he "de-sensitized" it. anyways yea i used the whole "oh well get better mpg's out of it and it will pay for itself in a few months" excuse to get my wife in the door. ahah and when we try we get good gas mileage ive actually seen it above 20 mpg's after the tune on a flat road. im actually using the whole better mpg excuse to justify a volant cold air so well see how it works ahah

Well I'll be damned. I emailed Justin, to see what we could do about getting the MPG's back up. Im thinking that I will start with having the AFM reinstated, seeing if that will help. Im hoping I wont lose any performance out of it though. LOL, hopefully not.
I will keep you guys posted. Im excited about getting everything dialed in, kind of the perk of having a custom tune. I appreciate any other comments you guys might have!

Ok, so heres an update...
Went to Vegas this weekend for the UFC fight, (Couture is the shit!), so I got a chance to stretch the Kon out a little, and see what kind of improvements the BB tune has done. Earlier in this thread I mentioned that the fuel mileage wasnt improving like I had hoped. Well after a few emails back and forth with Justin, I found that my driving style wasnt right for the tune, and that I had to drive a with a little more "gusto". In doing so, in town I saw a bit of a jump, back to stock numbers... keep that in mind.
Now, when driving to Vegas, from where I live, I have to climb out of two valleys, both multi-mile high % grades. By the time I got to stateline, the average MPG was showing 14 at best. When I fueled up, I double checked the reading with my own calculation, and was surprised to see that I had actually gotten 17 MPG. Which I was happy about, and the wife was satisfied.
So, Im thinking that I might have acheived my 1-2 MPG average gain, but for some reason the computer isnt calculaing correctly. Now I know though... BTW... the strolls up the grades were extremely effortless, especially in sport mode. It kept the tranny kick down pullin when I needed it. Even had to do a spirited pass at 60 MPH; by the time I passed the Honda on the hill I was grabbin 90 MPH... WHEW. Man I love this tune.
