Winter came fast in MN!

I'm glad I checked the forecast, and got my snow tires on last night!  

About 6" so far. Supposed to keep snowing the rest of the day.

Got a fairly conservative "Stage 1" road tune on my 2011 WRX. Baseline and after tune information is included. Only changes to the car are an SPT Cat Back Exhaust and the 16" steelies and winter tires. RomRaider log was used to create the dyno plot using Virtual Dyno set with CF=1 (which makes Virtual Dyno read similar to COBB's Mustang dyno, see below). I'm very happy with how the tune turned out. Much smoother and pulls noticeably hard through the low/mid range and up to the top end. Torque increase is very nice

Just for comparison, here is how my car's pull, calculated on the Virtual Dyno (CF=1), stacks up against COBB's Mustang Dyno baseline runs on 08+ STI's and 09+ WRX's.
