Hi, the tune is $490 and we include free updates forever!
No it wouldn?t void the warranty.

The dealer and their tools will never know the tune is in the vehicle.
We build our tunes from the stock calibration and the dealer doesn?t have the ability to see the changes.
They can only do full flashes.

We tune all GM trucks 96 and newer.

You can expect some nice torque gains and increased mileage.

If you understand how to do the tuning you'll know what to look for. With a Tech 2, I could tell if the programming is altered in about 1000 feet. Unless the tech has a reason to use the Tech 2, suspects a different program, and knows what to look for, you're safe.

I know Allen fom Nelson Performance. He has been programming for a while. We tested his programming for an article (i.e., mail tune) versus an in person tune and Allen did pretty well.
