We have identified the problem and we did duplicate it here on our in house LBZ truck.
Our tuners are working on a revision as I type this, I would hope to see it done this week.

Thanks

Had the same thing happen to me today after a reflash from the dealer .
put the 65 tune back on and motor knocked bad shut truck off and restarted it .gave it some fuel and it reved way over 3000 before I got it shut down.hope it didn't hurt anything it is a 2007 lbz.this was scary hope they get it fixed soon .

my 06 LLY has some problems also that you said that you were working on. mine falls flat on its face at random times kind of reminds me of low fuel pressure or a bad fuel filter...has cost me a lot in fuel filter replacement..also while accelerating at different speeds then leveling off to hold a speed say around 55 it jerks and surges ...kind of reminds me of a gas engine fouling out or something...any updates in the works..

Gentlemen, I discussed this today with our tuners and engineers, and they have confirmed they are working on a fix as I type this.
These types of things are sometimes beyond our control, because when GM releases these new calibrations that we have never seen before, we have to re-engineer the tunes to work with them. This is almost as much work as creating the tool from scratch.
The new update should be ready in the next day or two, fortunately for all of us, we have an in-house LBZ here to test it on so we will know right away if it is fixed.

Thanks

once again......" a day or two" and it has ended up being almost a week.....i know it may take time to find the problem and fix it, but shouldn't tell us something and then not do as you said you was, no offense to you mike or other technicians......this is just diablosport's problem.....

The problem has been identified and fixed here in testing.
The new revision should be up by tomorrow.

Thanks

Once you guys have the update to r19 or whatever you will call it, is it recommended that we up date the programer even though we have not been reflashed by GM?

I had my Sierra in for a steering issue about a month ago and the dealer stated there was no reason to update my ecu because there were no drivability concerns nor recalls that applied to my 06 LBZ. I am very happy with r18.

Thanks.
