The first step for installing Power Pack 1 is to remove the stock paper air filter.
After removing the 2 clips, the stock air filter slides out and the new K&N panel filter slides right in. This took all but 10 seconds.
Compared to the stock paper filter, the K&N panel filter has much shallower and less restrictive ‘pleats’.
Ford’s Mustang GT Power Pack 1 is easily installed by changing out the panel filter and uploading the new calibration to your car via the included Ford ProCal Tuner. Before we tested the full PP1, we decided to do a few pulls to see the gain in power from just the panel filter alone.
Ford advertises a 13hp & 16lb-ft of torque improvement over stock which is around what we’ve seen K&N air filters do by themselves on our Project E90 M3 (which picked up 13.84whp), Project Dodge Viper GTS (which gained 14.55whp), Project Lexus IS-F (23whp gain), and a Supercharged 2010 Roush Hammer (which picked up 20.07whp).
Needless to say, we are big fans of K&N filters here at MotoIQ. So, let’s see what a K&N filter did to our 2016 Mustang GT:
Stock vs K&N Air Filter
The K&N drop-in panel filter picked up 7.37whp at 6,500rpm and 7.28lb-ft of torque at 4,000rpm. The K&N air filter filled in the stock Mustang’s factory torque dip between 4,000-5,400rpm with an average increase of 12whp and a maximum gain of 19.14whp and 18.61lb-ft of torque at 5,400rpm.
A peak gain of 7whp/tq and a maximum gain of 19whp is a massive increase for the price of a $55 air filter and a 10-second install. Since we didn’t pick up the 13-23whp peak gains that we saw in our M3, Viper, and IS-F, this leads us to believe Ford’s OEM air filter design, layout, and airbox is far more efficient and better engineered since the gain wasn’t as big.
Now that we saw the improvement from the air filter, we were very interested in seeing how much more Ford’s proprietary calibration would do to the 5.0L Coyote V8 since there’s now only 6HP to be gained based off of Ford’s 13HP claimed increase from PP1.
To complete Power Pack 1, we installed the Ford ProCal software on our computer, connected to the internet to retrieve the proprietary software and upload it to the car.
Stock vs K&N Filter vs PP1
After turning the rollers, we were impressed to see a peak-to-peak gain of 11.75whp and 16.46lb-ft of torque over just the K&N air filter. This now puts us as at a 19.12whp & 23.74tq increase over stock, which is 6whp more than Ford’s advertised claims.
The more aggressive calibration tuned for 91+ octane picked up some significant torque in the mid-range and shifted the torque peak from 3,900rpm to 4,300rpm for incredible 30.07whp and 36.74lb-ft of torque maximum gain over stock. It’s interesting to see a prominent torque increase in the 4,000-5,400rpm range which used to be a dip in the car’s stock form. There’s also a nice 5whp and 11lb-ft of torque average increase from a very low rpm below 2,000 to 2,600rpm. Meanwhile, redline was also raised from an actual 6,800rpm stock rev limit to 7,100rpm to improve area under the curve.
For $599, Power Pack 1‘s 19.12whp increase is one heck of a value at $31 per horsepower which is significantly better than the commonly held rule of thumb that says it will cost $100 per naturally aspirated HP increase. As a (he won’t admit – humble) tuner himself, Ken from Palm Beach Dyno was impressed with the gains from Ford’s calibration and commended them for being able to achieve these numbers and close the gap to what most of the aftermarket is able to do, while remaining 50-state legal and under the factory warranty.
