hey guys and gals. im looking into this open ecu, and my roommate might get it over an AP to go stg 2 in his new psm 06 wrx. but will the dealership be able to tell that u tuned it? i know thats a benefit of the AP u can go back to stock setting and they wont know. not sure if it would matter since they would see the turbo back but its something to worry about.
