performance chips direct This is a skam and they should be jailed walnut, California
I bought the stage two chip set, Installed it and used 93 octange gas and this chip did nothing gas milage increased by .67 miles per gallon but cost more for gas than stock. I have tried many times to contact them never been able to. TO TOP IT OFF my check engine light would not go off. I riped out the s**t and noe running stock BIGEST mistake ever. GLAD to live in the USA where everyone has a chance to rip someone off and never have to pay thier dues. GOD BLESS THE F***IN USA
