2007 Yukon Denali 6.2

[phizzle00]

So I am looking at purchasing a programmer, but I cannot tell if it will adjust the shift firmness or the torque mgmt (which to seems it would be very important). I have seen several conflicting answers. I have seen a lot of "we are working on it". I have seen some claims it has it. If Diablo does not do it yet who does?
How does diablo compare in HP gain to the competitors when running 89 gas?
What else should I know about programmers? It seems like Diablo has the easiest process to get support, but what else should I know.

Sorry if this has been answered somewhere already, but I cannot find it if its there and Im fairly novice about programmers.

TM is reduced int he tunes already.

Shift firmness and shift point control are coming in a future update.

Our 87 octane tune will pick up about 15-20 rwhp on the 6.2.

Any update for the 07 Denali? I am looking to buy a predator for mine also. Can I turn off the TM like I can on my 04 silverado? How much power with the 93 octane tune? Data log? What can this thing do for the 6.2L?

thanks.
