Was the first day of fall, but with the ambient conditions that were present you would not think so. Another hot and humid day in Kenner, LA. We were working today with Scion tC as we installed a transmission on it and was adjusting the clutch on it and driving it on the street.
Got a call in the morning with a client that was wanting some one to look at his 2013 Subaru STi as it was not performing up to its standards. Managed to squeeze the client in at noon and told him that we usually calibrate the cars at nights since it gets really hot in the shop. He was coming in from MS and driving thru town on his way to Lake Charles and decided to call us to help him with his ride.
We moved cars around at the shop and got the AWD Dyno Dynamics ready for his arrival. Placed the vehicle on the dyno and got it ready to see what we could do to help matters.
2013 Subaru STi with stage 2 mods:
Stock engine / Cobb intake, APv3 /Grimmspeed Upipe, TMIC and catback exhaust
Tial BOV with EWG / Air pump delete / Cobb Fuel pump
Ambient conditions were 103F / 43% humidity and 30.03 Baro
Test performed in 4th gear
The vehicle was previously etuned and the client wanted a dyno calibration instead so we proceeded to accomodate him as he had some DTCs present that needed to be taken car of which were affecting his fuel trims and his over all WOT fueling.
Before the dyno pulls were done we checked the oil level and also discovered that we needed to add a quart of oil to the engine. In comes some Amsoil XL series 5w-30 to the rescue.
Before and after resutls from the tuning session. 261awhp and 288awhp was achieved.
Dyno jet simulated number vs boost which just hit 20psi and tapered to 16psi.
In conclusions the client was very happy and we thank Chris for trusting us with his ride and having patience in this hot and humid day which was not easy day to calibrate an engine.
