Compounding our already stellar calibration, we at JDM Engineering introduce our stage 1 upgrade kit. With the addition of the Whipple cold air kit, we remove any restriction in front of the turbochargers allowing for more airflow which equals more power. Also, due to a colder intake air temp, we see a gain in power on the initial hit and drastically reduced heat soak in subsequent pulls. Further chilling the air charge is a Whipple Mega Cooler, which makes heat soak a thing of the past. We include a set of Motorcraft SP-550 plugs to keep detonation at bay at all loads the vehicle may see.
Expect a modest bump in fuel economy from our upgrade kit of about 1-3 mpg, and seamless driving experience regardless of putting through a drive thru for a latte, or tearing through some terrain in the desert. With the JDM Custom Tune included in this upgrade kit, the 10R80 Transmission is put to good use and refined to no longer hunt aggressively for a higher gear when driving gently, but there is zero hesitation when rolling into throttle offering the right gear at the right time. Expect refinement only gained from being in the business for over 20 years at JDM Engineering.
