I put one in mine after I purchased the car ,on basic settings the car felt a touch better but nothing sensational ,as soon as I started playing around with the settings it did nothing except throwing the check engine light made the car completely unreliable . Save your money .I bit the bullet after I changed the downpipes and put new turbos on and had the ecu tuned
