skywalker,

Do all the ECUTEK programmers have the exact stock maps so if I wanted to sell my WRX to a blue haired old lady in a few years I could have the ecu reset to exactly the way it was pre-ECUTEK?

Also, in your mapping experience, what differences have you found between: (a) a stock WRX with ECUTEK and (b) a WRX with a catless upipe only and an ECUTEK?

Thanks again for your helpful information.

Dave
