Car is 2012 WRX sedan:
Currently, I have the Cobb SF intake/box and their ots stage 1 on accessport, and the nameless performance muffler delete setup. I'm gonna order the cobb catted dp, and do the stage 2 map...was also really leaning toward doing the process west top mount ic, and then getting it pro tuned. If I'm gonna go beyond the dp and stage 2 to add the tmic and protune, do I need to start upgrading the fuel system at all prior to wrapping it up, or am I ok unless I go beyond the listed mods??
fwiw, I'm in Northern CA and can't get better than 91 anywhere...and it's tuned by cobb on that AZ, NV, CA tune cause apparently our gas is that bad
thoughts at this point in mods??
