What kind of power programmer should I use?

[eddiemcnally]

I have an 06 H2 and want to get a power programmer. Any suggestions? I had one piece of advice and it was to get a Hypertech E-CON. Im Going for fuel economy and a little more power! What's the best one for the H2?

Thanx, Eddie

I have the Cortex and love it.

It has Fuel Saving
High Octane and normal octane tunes.

I also have a Superchips Cortex. It's the only programmer I've ever had but I have zero complaints.

[eddiemcnally]

So does the super chip cortex actually give you more power and better gas mileage? If so, what are the numbers?

Thanx

I was told by my mod shop to go with Hypertech E-CON.

I've been running a Hypertech chip programmer and added about 2-3 miles to the gallon 4 years ago no problems with it ! Put it in at 34,000 miles and have about 160,000 on it now !:perfect10s:

One concern is the use of 87 or 91 octane with the programmer! Hummer mech says do not use 91! Is that because it's factory tune? The programmers usually give you the option! Will it hurt to use 91 on the tune?

Thanx, Eddie

Diablo predator. Awesome programmer, tons of features with the ability to turn off TM, and add custom tunes down the road if you begin adding performance upgrades. :beerchug:
