No they do not work. Sorry, we have tried to find ways around it by using resistors and such to barely retard the voltage from letting the stock ecu read WOT. At WOT all piggy back controllers are cut out as the car goes into closed loop mode at this point. Just spend 150 more and purchase a Greddy e-manage or something. I know they are good on other cars but have not heard anyone try one proteges yet.
