I'm looking at the Hypertech E-Con to improve fuel economy and a little more horsepower/torque. I'm curious if anyone out there had tried it and if it would really work on my 2005 H2.

 

No I have not.

 

I was looking for this as well to install on '03 H2. Did anybudy tried it yet?
It seams like a nice gadget.

 

Yeah, I've been looking at it too, but have been waiting see if anyone has it or read a review on it. I have not found anything that would convince me to buy it yet.

 

i had one on my h2 and so no difference only that i could
adjust my speedometer for my larger tires. *** far as
performance and fuel economy couldnt tell a difference.
now ive sold that one and loking to buy a better one

 

If you had a larger tires instaled that would normaily increase gassconsumption, right? So maybe this gadget works but you didn't realized becouse it spended same gas as with smaller tires. I'm not expecting that will save more then 5% of gass consumption.

Are there any other gadgets on a market, taht can increase gass efficiancy?

 

You can park it for a couple of days the would improve your monthly gas consumption. NOT! Gas would have to get more than $5.00 a gallon for me to think about parking my H2 or if the HX comes out first, but at this rate it looks like gas will more likely hit $5.00 first. [:'(]

 

GP you can try air intakes or a high flow muffler but you will
spend a lot of bucks before you ever see any significant results!! but that hasnt stop me, just got a new flowmaster
installed and sounds great

 

Bigger tires won't effect you MPG unless you go huge like with 37's or something bigger. It only effects you Speedometer/Odometer which makes you THINK that you are getting worse mileage. Once calibrated you more than likely will be getting about the same MPG.
