Be careful when choosing I looked into the chip mod that has both air sensors seemed to be the one to get it is the 3rd gen and will provide the most gain the more info that is give to the ecu the better the engine is tuned good luck let me know if there is the gains they say. I am leaning towards sending my ecu to rentech to have re programed about 2500 euro
