2015 Subaru WRX – Protune stage 2
Category : Automobile Performance
As always thankful for getting a chance to meet new people and this was no different as I received a client at the shop that day from the state of MS. His vehicle was a 2015 Subaru WRX on stage 2 mods. He was using a e-tune and was tired of going back and forth and not being able to get the tune spot on.
Car came in and we first proceeded to do a smoke test on the engine to make sure we did not have a boost leak before the session. Boost leak test came back negative and then seeing that we proceeded to put the vehicle on the rollers.
Mods on this vehicle were:
Grimmspeed EBCS / Grimmspeed CAI / Perrin Chargepipe / Tomioka Racing downpipe / PRL tgv and egr deletes
Cobb Accessport v3
Ambient conditions on the day were: 74F, 45% humidity and 30.13 baro. Test runs were in 4th gear.
Purple line was as the car came in, hitting 20psi and tapering to 15psi.
Grey line was at the end of the tune, 19psi tapering to 16psi. On this run i let off the throttle after 100mph due to seeing higher IATs. This was later corrected on the highway after some runs in the real world.
These were dyno jet presented numbers.
