This what i have heard... not 100% if its true. you can put back on the stock maps, but if subaru questions your ecu they can mail it to soa and they can run tests to see if it was ever changed. and if it is then youre kinda ****ed

personally, i wouldn't until the warranty is done. my friend literally called me an hour ago. was driving to san francisco and blew out his engine. i know it was from his tune because he doesnt get it done professionally. thats something to think about i guess.

my warranty is up so im saving for it. but im definitely going to a reputable tune shop. someone on here made me realize spending the extra 150 is worth not having a blown engine.

Not having it done professionally is usually the problem. Since I am "in the market" for a WRX, I've done a crap load of research on tuning and warranty problems. 80% of the "bad situations" that I have heard of are due to amateur/DIY tuners. I have also read about several instances where there is a tune professionally done and if the problem with the car is unrelated to the tune, the dealer doesn't care. I have also heard of a few instances where the pro tune company "untunes" and is undetected. At the other end of the spectrum, the DIY tunes usually cannot properly untune.

That is just the overall summation of what I have read so far. Set me straight if I am wrong.

from what ive heard its hit and miss, some dealers you can return to stock and they will fix the issues, others you can return to stock but if they link the problem to the aftermarket parts you used they can refuse service

There is pretty much zero difference in how well an amateur can put the car back to stock vs. a shop. Neither can do so perfectly.
