I found this on the big auction site from a company out of Canada claiming gains of up to 30hp and 30 ft lbs. of torque. No dyno sheets posted and it sounds like it is just tricking the ecu to adjust A/F ratios.

Someone buy it lol

 

That will for sure mess your car up untill you unhook it

 

absolute load of crap! If you google gforce chips their are sooo many negative reviews and angry people that say they cant return the product or get their money back. If im not mistaken you clamp the leads onto wires going to the maf sensor

 

it could be running rich and you end up blowing it up!

 

They even clearly state it will work or money back guarantee! Sounds like they are just taking advantage of people and running, sad!
