What performance gains can I expect for an 07 GMC Denali 6.2?

You will pick up about 20-25 rwhp along with a healthy gain in torque and throttle response in the lower rpm ranges.
You may also see a gain of 1-2 mpg on the highway.

Thanks

Mike,

Is the gain of 20-25 rwhp based on 91 or 93 octane gas? I noticed that the Predator for my Denali (U7194) can only program for 91 octane for Corvettes. All of the gas stations in my area seem to only carry 91 octane...
Also, what is a healthy gain in torgue, 5 or 50 ft/lbs?

Thanks

The gains are based on a minimum of 91 octane.
There is also a less powerful 87 octane tune available.
By healthy I mean 30-35ft/lbs.

Thanks

Do you have a dyno chart for the GM 6.2 (Denali and Escalade) that you can share?
If not for the 6.2 maybe the previous 6.0

Thanks

I'll send you one for the new 6.0

Thanks

[quote="mikel"]IHave you had a chance to email the dyno chart yet?

I know the previous poster was asking about the 6.0 dyno chart. Do you have a dyno chart for the 6.2?

I have an '07 NBS Sierra Denali and I'm curious how different the dyno is with and without the Predator.

Thanks!
