Does anyone have any experiences with the performance chips sold on eBay and other sites that promise more horse power and
better gas mileage - claiming the factory sets the fuel mixture too rich.

Thanks,

JUNK!

What helps are items like the programmers like the EDGE, SUPERCHIPS etc.. These can help with gas mileage and you can updated your fuel etc.. After doing mods or for the gas you prefer to run in your vehicle etc..
