I met a new friend with a 2011 WRB STi with a SPT CBE and we ran. I pulled on him really bad, just goes to show how a driver mod really counts and im stock. Now i have K&N filter in my stock airbox though. Im currently in the process of helping him on how tame the beast!!
Also I ran my buddies 09 wrx with Cobb intake, invidia turbo back exhaust, tomei unequal length headers, grimmspeed uppipe, grimmspeed boost controller and he is protuned and still pulled! Surprised my flaps are on still. LOL He is about 300+ at the wheels.
I love the new STi.
*disclaimer - we ran in "Mexico".
