The fuel system is completely different and require different tuning. Some vehicles sold in states bordering California are California compliant vehicles with these same changes. Before ordering tuning, you will need to determine whether your vehicle is a California version or not. California vehicles have an extra control module on the floor below where the ecu is mounted. (see picture below) Also, there is no return fuel line from the fuel rail on these models. Tuning is available for these models under different listing. This product requires the customer to ship their ECU to Geiser Performance along with a printed copy of your order. If you want the ability to flash your own ECU, change tunes, return to stock, datalog, etc, please see Maptuner X. PLEASE INCLUDE YOUR VIN NUMBER IN THE COMMENTS SECTION AT CHECKOUT. WE CAN'T TUNE YOUR ECU WITHOUT THIS.
