I recently brought my 2013 STi to John at Akuma Motorsports in New Jersey. I couldn't have had a more positive experience. John and his staff were friendly, helpful and professional. I highly recommend anyone in New Jersey to pay them a visit if they're interested in anything regarding performance/installation.
Prior to meeting John and his team early on a Saturday morning, my car had a Cobb Catted Downpipe, Cobb Heat shield, K&N Drop-in filter and a Cobb AP OTS tune. I was going in to Akuma Motorsports for my new Q300 CBE installation along with a DW65c Fuel Pump install. After the install my car was strapped to their Mustang Dyno and pro-tuned by John.
My car made 287whp & 334wtq @19.8psi
