SO I been researching that the 2015 and 2016 WRX FA20 Engine had a power stutter between 4k-5k RPM for those who currently have a 2017 model year. Does this issue still persist or did Subaru fix the issue? Otherwise I know I'm looking at a Cobb Accessport to retune the stock map after the break in period.
Still waiting for my 2017 Limited CWP WRX to arrive! (ordered it on 6/7/16)
