Customer came in after purchasing a turbo Scion XB. The previous owner setup an Ebay FPR in addition to the STOCK FPR. Bottom line, The car ran horribly ! After burning through tanks of gas, terrible partial throttle, and constant fouling of plugs he knew something wasnt right !

So we started the process with new plugs, Aeromotive FPR, Proven Power return line, and finished it off on the dyno !

Pics of the install !
