2015-2021 Subaru WRX (Manual Transmission) Stage 1 OTS Tune by MAPerformance
MAPerformance has been manufacturing, building and tuning modern fuel-injected performance platforms since 2006 and from our first test drive of the 15+ WRX we knew this was going to be a killer platform. After extensive development and refinement, MAPerformance is able to offer support for owners of this tuning solution. If you already own a COBB Accessport device, the MAPerformance stage 1 tune will be a great next step.
With the update of COBB Custom Features Gen 2, we have been able to take advantage of many more updates to even further enhance our OTS Tunes for the 2015-2021 WRX. We now utilize load metering via Speed Density and a slew of other worthwhile updates that improve the consistency, precision, and drivability of these OTS tunes.
