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

Event: Stage 1 Road Tune
Location: MN
Ambient Temp: 40F
Elevation: 725ft
Weather: Cloudy
Road Conditions: Flat
Tires: General Altimax Artic 215/55R16

Car: 2011 WRX 5 Door
Tuner: Nuke
Dyno Info: Virtual Dyno - CF=1
Transmission: Stock 5 Speed
Gear: 3rd
Target Boost: 17psi
Target AFR: Unknown
Fuel: 91 Octane Unleaded
Engine/Power Modifications: SPT Cat Back Exhaust
Driveline Modifications: None
Suspension Modifications: None
Other Modifications: 16" Steel Wheels
Baseline:
Peak HP at RPM: 242hp@6,000rpm
Peak Torque at RPM: 261lbft@3,000rpm
Stage 1:
Peak HP at RPM: 252hp@6,100rpm
Peak Torque at RPM: 297lbft@3,400rpm



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.
