I bought the V2 to be able to reflash my truck in case the dealer blew up my tuning. It's a pain in the ass learning how to work it, getting logs for Justin to look at, and then flashing your own truck. I still need to get him another post tune log to maybe do another tweak on the transmission. BUT, today I got the first opportunity to test the tuning against what should be a perfect measuring stick. I lined up with a NBS Escalade that would be the same 6.2 6-speed drivetrain as me. From zero to 85-90 mph I put AT LEAST 5-6 lengths on him and it was getting worse the faster we went. He was sure I had a blown 5.3 until I showed him it was a stock 6.2 with nothing but a BB tune. To top it off, his truck was 2WD and mine is a 4X4 with lots of junk in the back including the rear seats and every possible option. Everything else is a waste of money.
PS: Try that with a Superchips or Diablo tuner. Good luck.

The transmission a bit more like you had hoped it would be?

Yes, but still not what I'd like. I posted the problems in the Diablo tuner thread and it's a factory problem. the TSB fix made things worse if nothing else. Justin's tune has helped, but not solved everything. The upshift is harsh if you roll up in speed and have to get out of the throttle just before, or as it shifts on the 1-2 or 2-3 shift. It happens a lot in traffic. I still have the flair when it's not all the way warmed up, or even if it's warm but has been re-started after parking it and hasn't been through a couple of up/down shift cycles. It's weird. I wish I had never had them do the damned TSB "fix". It's also a little harsh on up and down shifts while in tow/haul mode. They know there's an issue with the 6-speed trans since they issued the TSB, I just don't think they know what exactly is the problem, and they sure as hell don't know how to fix it.
Gotcha, yeah the dealers sometimes will just use a band-aid.
