    I have a stage 2 catless 2012 wrx. I brought it to the dealer to get the update done with an oil change. I unmarried the accessport before going inside the service dept. I handed them the keys and when the car was ready, I installed the accessport once again before leaving the lot and everything ran smoothly as it should. I dont think anyone who does this will have a problem either since I think the accessport maps will overwrite anything the dealer has done. The only plus/reason to doing this is that you had the latest stock ecm image backed up to the accessport (at least that's how I think it goes).

    Just an update and question.

    Just took my stock 2012 WRX in for 7500 mile service, and had to have this flash performed. After i received the car back i feel like the throttle is a bit delayed. the lower RPM's don't have as much oomph.

    Anyone else have similar results or am i just crazy?

    I experienced exactly the same thing. I was told to wait a day and let the car relearn my driving habits. Within 24 hours I felt the car returned to its previous state, so give it some time and see if it makes a difference.

    you were right. Feels totally fine now. Either it fixed itself or i am just used to how it drives.

    So i have one more curiosity im hoping someone can assist with.

    Of those of you that had sport tunes, did your dealerships even notice?
