I have a 2012 WRX hatch and am ready to spend a little more cash on my car (around $1k)and was looking for opinions on which way to go. DW currently has a deal for fuel pump + 850cc injectors for $560 which I would install and get a new custom tune, or I was going to pick up a process west tmic and install it without a new tune. Currently I have a turboxs catless dp, grimmspeed ebcs, and protune running 18psi making 276whp/286wtq on mustang dyno. I read about the wrx tmic crappy out under higher psi so was considering the pw to be on the safe side. This is my DD and my goal is to get the most out of it on the street and track (1/4 mile).
