not at all, not even sure what problems they could have, but with the car being stock, Subaru will fix it. I am just going with Subaru gives me. Now when I get out of my 100k mi warranty, I'm likely going to go stg 2, but that is a couple years away. But at that point, if I see something I really want more, my car will be worth more cause it is stock.There's lots of pinheads with Mustangs where I live, but there seems to be more pinheads with WRXs, not that that's deterring me, I'm just getting tired of turbo cars and want either a lightweight higher revving n/a car (brz) or a relatively cheap and reliable V8 car (S197 Mustang)
I'm actually thinking about unmarrying my accessport and going back to the stock map, you don't seem to have any problems with it
