Applications: 09-23 5.7L, 11-23 6.4L HEMI, Mildly Modified
With some of the most experienced Late Model Gen 3 HEMI tuners in our group, HHP continues to be on the leading edge of performance tuning for today's late model EFI production cars. The tuning market is flooded with shops that possess the programming to write the tunes, but tuners that have the understanding of how these engines operate are very few and far between. With years of experience building and tuning a large majority of the fastest HEMI's on the streets and at the Track, let HHP apply their knowledge and experience to your vehicle.

To achieve peak performance, this tune includes but is not just limited to:
- Optimization of Fuel tables
- Optimization of Timing tables

Use Of Wideband Air/Fuel Ratio Gauge: Recommended but not required. In order to precisely dial in your full throttle fueling, an aftermarket air/fuel gauge is needed. While we do not require an air/fuel ratio gauge for this level of tune, use of one will increase our precision ensuring your vehicle is at it's maximum performance. We recommend the AEM 30-0334 for 2008 and newer vehicles for seamless plug and play operation with your HP Tuners or newer Diablosport device.
*NOTE: To speed up your order, we will require a copy of your stock engine/transmission calibration to be sent in to our tuning manager. These stock backup file(s) or reads can be emailed to tuning@hhpracing.com with your current modifications list and your approximate elevation/DA for your area (i.e. close to sea level, 5000' Mountainous Terrain, etc.). For RTD Customers, please use invite code DCDF-1615 on your TDN application.
