I have a 07 H3 and I love it!! I read that I can increase ***** power and milage by doing exhaust. but then I saw the add for the G FORCE chip and it sounds convincing?! does anyone have any suggestions? or do they have one? thanks

 

Pure snake oil AFAIK.

See this thread https://www.hummerforums.com/forum/g...chip-h3-25840/

 

so a no go?! wat would be the best way to improve mpg?

 

I am thinking about getting the same chip, I understand you can gain about 60 hp and your mpgs by 6/7 mpg. Sounds too good to be truth

 

It also has a sensor that can tell when you are hungry and it gives you free money and, and , and .............

Snake oil people, take the time and READ the link that bflank so kindly posted for you.

 

I canceled my order for that chip, it is a scam.

 

I dont know much about Hummers or GM for that matter but when it pertains to "tuning" an engine is an engine is an engine. I have a 650 rwhp cobra that I tuned myself with an SCT handheld and some basic software. Granted I dont see anyone getting those kind of gains out of anything that is considered a "tune in a can" (which refers to any kind of general chip or flash program with a preset program not custom to your actual vehicle).

When my 2003 Cobra was stock it was supercharged form the factory at around 400 hp. Now these cars have quite a bit left in them if you can reprogram and upgrade your exhaust... I upgraded my exhaust and did a "tune in a can" much like the one you are inquiring about.... I actually lost power... That being said I leaned out the fuel tables and added some timing and went from about 390 to 415-420. Keep in mind this was on a forced induction car not on a naturally aspirated motor. 60hp gain is rubbish and laughable and I would love to see how this company can get away with such a bold claim!

If you want to get the most efficiency out of your vehicle call a local dyno shop or find a tuner that can tune your vehicle, and get a handheld that the tuner can use and get your vehicle a custom tune for each grade of fuel you have in your area. The juice probably isnt worth the squeeze but every little bit helps.
