I have a 2006 Hummer H3 (automatic)
I was wondering if anyone has used any of these "performance chips" and if they really do work or not. I am looking into the g-force performance chip GFChips High Performance Chips Factory Direct
They install into the engine bay and are connected by 2 wires to the IAT sensor.
Supposedly this will give my H3 better performance, increase HP, increase torque, and possible better gas mileage.

DO THESE WORK???? ARE THEY WORTH THE $69????

Thanks in advance for all responses.

 

sad to say i fell for this garbage too. this is a scam , they have lawsuits in california against them . people on this site gave me the info. i needed. I sent it back and they credited the full amount.Some were saying they would charge a 25% restocking fee
