Dyno Tune Thursday – 2018 WRX Stage 2 with EGR & TGV Deletes

Hooked up to our Mainline Prohub Dyno for tuning was this 2018 Subaru WRX that was custom tuned by TurboTek Tuning. The car had a Catted J-Pipe, 3-Port EBCS, Air/Oil separator along with EGR and TGV deletes. From our experience, we’ve found that 94 Octane makes a large difference in these cars with regards to power and knock resistance. When running 91 octane fuel we’ve observed FA20 WRXs to be very knock limited, therefore requiring us to de-tune the vehicle to prevent knock from happening.  With 94 octane in the tank we’re not as restricted and we’re able to maximize the performance and safety.

  • What sort of numbers do you usually see from a Stock ’18 WRX (FA) with this dyno? How much of an improvement did these mods/tune make?
