Well, I put my Utec on my all stock '02 WRX(which will be for sell soon, very low miles) in mid-November and love it. Now I am first on the list at my local dealer to get an '04 Sti and am wondering if my Utec will work on the Sti. Haven't been able to talk with anyone at TurboX. Anyone know?

What exactly does the Utec do? Is it just a piggyback ECU control module? For boost, fuel, etc controls?
gotcha, i figured something like it.
