2015 Subaru WRX – Stage1 mapping

Got a local friend that hit me up asking me for some help on his Subaru. He has issues of the car stalling at stop signs and stop lights. Got the car in and looked at the plugs and they were fine.

Checked and see and this car has a AEM intake with box but with no calibration.  Seeing this we ordered a Cobb Tuning APv3 and installed it.

Made some adjustment on the dyno over the OTS stage 1 calibration and was able to find a little power enhancements and now no more stalling on stops.

Ambient temps at the tune 92F, 70% humidity and 30.03 Baro.

Test was made in 4th gear.

Before an after the Protune, fueling was very inconsistent with the oem calibration and now its dialed in. Managed to make the turbo spool a bit quicker
as well with the calibration move.

Baseline pull in blue and then the other two lines are after the calibration on stage1.  These are Dyno Jet simulated numbers.

Thanks again Forty for trusting us with your ride!
