It seems too good to be true... http://www.gfchips.com/hummerh2.aspx

 

I'm curious about this as well.

I obviously didn't buy my H2 because I overly concerned about MPG.

I traded in my Chevy HHR for the H2, so, I really gave up great MPG for the H2, but, I am still curious about this chip.

 

Wow! if what they are claiming is true, it would be an absolute miracle.

I highly doubt anyone is able to get 60hp and 4-7 mpg from a stock vehicle with a tune or chip. I wish it was possible. But I wont be buying one.

The best in the business I.E. Diablosport, Hypertech, Superchips, Etc... All claim roughly 20hp running premium and less with 87 and 0-2 Mpg. And in some cases do not gain anything. Every vehicle is different and require a little different strategy as far as tuning is concerned. These guys do the best they can do without the actual vehicle in front of them on a dyno.

If you do try one of these chips I am interested to see what your results are. That's my two cents, Good luck.

For info I just installed an AFE intake and am averaging a little over 1 mpg better on the highway. It went from 12.1 to 13.3.

 

WOW!! 4-7 increase in mpg. I got to see it to believe. Just 4 is alot. But there claiming 4-7. WOW I would love to see someone get 7 more.

 

I have heard nothing but the word "joke" when this chip has been talked about. There is no way it works.

 

That is my thoughts but am hoping for replies from people that have tried it...I think it's bs for sure...Hoping someone chimes in saying it's true...lol

 

I agree & will not be buying one either. Lol no way this can be true!

 

Snake oil. The only extra power will come from the fact that your wallet is lighter.

 

Lmao that was funny!:

 

I tried one.......It took them forever to get it to me, and I did notice some performance increase. there was however, no increase in gas mileage. Save your money.
