my 2009 has a hypertech max energy right now, but i want to get the edge gyphon. can i see my hypertech? or is it junk now that it has been plugged into my trucks computer? also, has anyone made this change yet? want to know if im making a good decision or not, thanks
you may be screwed. I had mine plugged in, then returned it to stock, and when I tried to go back to a performance tune it would not even recognize my truck. Then customer service told me that I'd have to supply the receipt to them in order for them to re-program it for my- or any other truck. Without it, they wanted to charge me a couple hundred bucks as I recall. If you can, see if you can return yours to stock, then download the tune onto another, similar truck. Maybe offer a test drive to prospective buyers (with cash in hand, of course). Good luck. I'll never use Hypertech again.
