Does anyone have this?

Hypertech Hummer H2 & SUT Max Energy E-CON economy power programmer

I'm looking at possibly purchasing one.....the ad states 2-6mpg increase in fuel economy.....I was curious if it was true, before I dump a lot of $$$ on it.
I can buy it through my distributor so it saves a little, but don't want to waste $$$ if it doesn't work.....!!!!!
Any feedback would be great!!!

 

Ive always had good luck with Hypertech products. Right now, I have the Hypertech HyperPAC on my Hummer, and love it. Fuel savings.... Wellllll... It all depends on how you drive it after the tune. You'll notice A LOT of improvement over the stock PCM program. I changed the rev limiter, firmed up the shift points, etc... That with the K&N intake, its opened up a sleeping giant under the hood quite nicely.
Fuel economy... Havent seen it yet, but then again I am still playing with the added power a bit, and probably wont this tank. Although, the results I got from my Avalanche previous to this truck, were positive. I didnt get 6mpg out of it, probably closer to 2-3, but every bit helps. At these prices, it wont take long to regain a lot of that investment in fuel savings (Once I get my foot out of the floor that is hehehe)

 

I am anxious to see how it works for you. I want one myself.
