(Klaus?) After an "updated programming", some 03s and 04s get 13.5MPG?

[C5A4]

I emailed Diablosport asking about the upgrades in the programing and this is the reply.

QUESTION: [I have a Predator for my 03 Hummer H2. Hummer has just released a couple new software updates for the engine. If I upload my factory program back in and then take it in for service at my dealer once they update the trucks software will my Predator redownload the new updated software then install the performance tune?]

ANSWER:

We are aware of these new flashes and if you used the predator it would install the older revision, we are currently working on a upgrade in revision to accomodate this.
