Has anyon etried or heared anything about these gf power chips, are they legit or are the crap??

Thank You

 

Don't know exactly what the gf power chips is but I guarantee they are junk. All chips are, they all are false. Along with throttle body spacers and the fuel saver stuff to. Don't waste your money. The only thing that works is a Mopar High Performance computer, but in order to gain the most you have to upgrade everything else.
