Testing Airaid’s new 5.0 cold-air intake and SCT Performance tuning
By Steve Turner
We hope you tuned in for our story on testing the new Airaid cold-air intake system for the 2015 EcoBoost Mustang. If so, you know we were able to double down and sit in for the testing of SCT Performance’s preload tunes for the 2.3- and 5.0-liter S550s. This time around we started with the stock inlet and calibration and stepped it up from there.
SCT Performance’s Matt Alderman had already worked his magic behind the keyboard to create a preload tune for the Airaid MXP Series Cold Air Dam Intake System for the 2015 Mustang GT. However, for our visit he returned the car to its stock airbox and calibration for our baseline testing. Then he reinstalled the Airaid system and flashed in the preload tune via an SCT X4 handheld device.
You’ll be able to do the same, as this file will be preloaded on SCT devices. As such, you can just scroll through the tuning options and select the Airaid file for your Mustang. The combination of the freer-flowing intake and the preload calibration worked quite well. The car picked up significant peak gains and even greater gains under the curve. You can watch our test pulls here:
Once we had established the gains from the Airaid system and the preload tune, Matt decided to dial up a slightly more aggressive calibration, which represents what your tuner of choice might create as a custom file for your car. Adding it picked things up across the board, but we just narrowly missed surpassing the 400-rear-wheel-horsepower barrier.
Interestingly, Matt was able to get the car to make 406 at the tire the day before we arrived, but the weather was just a bit warmer. We were testing on a really cold day by Florida standards, so the correction likely shaved a little power off.
In any event, we can safely round 399.99 up to 400 at the wheels, and making that kind of power with a CAI, Cat-Back and tune shows just how great it is to be into cars at this point in time.
SCT will be developing tunes for a few other parts on this car, so expect to see some more product development right here on SVTP. For now, however, just enjoy the gains from the tune and cold-air intake.
