I was wondering if anybody out there had any experience with any or both of these tuners for the new Tahoe/Suburban/Yukon's? I currently have the Superchips Flashpaq and was impressed with the increase in power and fuel economy, but Edge's claims of HP increases have caught my eye. The most HP gains you can expect with the Superchips is 20 (to the wheels) and Edge is claiming 40 (to the wheels). Anybody have any first hand experience?

 

I have the Edge installed and I have yet to have it dyno'd so I can't back it up with #'s, but I do notice a little more get up and go on the performance setting. A 40hp gain is probably a bit of an exageration, unless it is under optimum conditions. Either way, I'm happy with my purchase.
