I'm selling a Utec for a WRX made by Turbo XS. I purchased the UTEC from ebay used and not yet know how it works but was told that the guy had in on the car for a year before he sold the car and the computer to me. I want to sell the UTEC beacause of a money crunch. Its a great mod for those hard core racesrs who want to increase horse power quick and mess with their fuel ratio. I am selling the computer for exactly the price that I bought it $700 shipped. Any questions call 1 (916) 370-5160---------David.
