DiabloSport Supports 2020 5.7 & 6.4L Dodge and Chrysler Vehicles


Just recently, DiabloSport announced its tuning capability of the 2020 Dodge and Chrysler vehicles equipped with 5.7- and 6.4-liter engines. DiabloSport brings performance increases by optimizing the engine timing and fuel trim while adapting shift responsiveness and crispness of the automatic transmissions.

DiabloSport offers a pair of tuner options to increase the performance of the Hemi. The first option is the Performance Kit that includes a DiabloSport Modified PCM for your vehicle and an inTune i3 Part Number 8345 handheld programmer. The second option is the all-new Trinity (T2) Platinum Performance Kit (PKIT). The PKIT features a high resolution, 5-inch capacitive touch screen, swipe functionality, appealing gauge designs, and the power that is the trademark of DiabloSport products. All this tuning power is available through a user interface, which is simple to operate.

The factory PCM is not modified and can be stored as a backup.

Regardless of the tuner selected, both come with pre-loaded performance and economy tunes. DiabloSport’s 93-Octane Performance Tune has dyno test results with proven rear wheel performance increases of 20 horsepower and 25 lb.-ft torque with the 5.7 and 20 horsepower and 18 lb.-ft torque with the 6.4 Hemi. Additionally, the tuners provide fine-tuning of the tire sizes, the speed limiter, the idle speed, multiple rev limiters, the throttle booster, fan temperature operation, fuel trim, spark advance, and the multi-displacement system (MDS).

DiabloSport has a nationwide network of Chip Master Revolution (CMR) custom tuning dealers that can build specific tunes for the added owner options if tuning beyond the “canned” tunes is desired. Since the DiabloSport tuners adjust emission calibrations, the tunes may not be street legal and may only be available for use on competition vehicles. It is best to check the state and local laws about the compliance of the tuners. Lastly, the products are not available for sale or use on pollution-controlled vehicles in California.

It features a high resolution, 5-inch touch screen that provides access to increased engine efficiency and power. The screen can be configured with gauge display of engine parameters, which is easily observed by the vehicle occupants. Above right: The T2 comes preloaded with high-performance tunes, but if additional performance is desired, DiabloSport has a nationwide CMR custom tuning network that can modify the engine tune to match the aftermarket parts installed on your ride.

Adding power to a Challenger, Charger, or 300 has never been easier. Take the time to check out Diablo’s latest tuner options and components, and you will be able to install additional power and feel the freed-up performance.

Above left: DiabloSport installed a 93-octane Performance Tune on a 2020 5.7-liter Hemi and gained 20 horsepower and 25 lb.-ft of torque. The performance increase was across the entire pull from 2500-6000 rpm. Above right: On a 2020 6.4-liter Hemi, Diablo added 20 horsepower and 18 lb.-ft of torque with the 93-octane Performance Tune. While the tune’s performance was slightly down under 2400 rpm, the tune out performed the factory parameters from 2400-6300 rpm.
