MAPerformance 2015-2017 Subaru STI Stage 2 Tune
We are excited about the official release of the MAPerformance Stage 2 OTS Tune! This Stage 2 tune was developed using our MAPerformance downpipe and air intake kit, to create an affordable solution that increases power & performance throughout the powerband while maintaining OEM like reliability and safety.
When comparing our Stage 2 Tune with the MAP Stage 1 OTS Tune, there are many advantages far beyond the improved sound and raw power. Not only are the power and torque gains inherently impressive, but it’s also important to note how much less work is required from the turbo and less stress on the engine to achieve the higher power levels.
Simply select your desired fuel octane from the dropdowns and fill out the "Tune File Form" above to take your 2015+ Subaru STI to the next level...stage 2!
