Hi everyone!

Just picked up my new to me 2010 Denali yesterday. It's my wife's ride, serving a dual purpose as the tow vehicle. So far it's the stock 6.2, and she'll shoot me if I do much to it.

That being said, I've got a Cortex 2950 tuner I bought for my G8 with the 6.0 and various mods. I know the tuner has a tow program on it, will that work for the 6.2? Is it worth doing, will I see any benefit out of it? Again, not really for everyday driving, but for a couple of the long trips we have planned towing the boat?

Thanks!

Steve

Not sure if you have tried the Cortex yet but I have the 2950 as well. I used to the tow program hauling my HHR from PA to FL. It definitely helped with pulling out and merging. I only have the 5.3. It does require you to run 93 octane.
