This DiabloSport Modified PCM offers a range of features designed to enhance your Ram 1500’s capabilities:
The DiabloSport Modified PCM is built to the highest standards of quality and durability. It features robust internal components engineered to withstand the demands of performance tuning while maintaining the reliability expected from a factory-grade engine control module. The unit is carefully modified to unlock the calibration without compromising the integrity of the original hardware, ensuring long-term dependability in a variety of driving conditions.
Its design allows for seamless integration with the Ram 1500’s existing wiring harness and sensors, preserving all OEM functions and diagnostics capabilities.
Installation of the DiabloSport Modified PCM is straightforward and requires no permanent modifications to your vehicle. The PCM is a direct factory replacement for the original unit located in the engine compartment on the right side of the firewall in the Ram 1500. Before ordering, you will need to provide your current PCM Calibration ID# to ensure proper matching and compatibility.
Once installed, the modified PCM must be programmed using a compatible DiabloSport programmer (sold separately) to load custom or pre-configured tunes tailored to your performance goals.
This modified PCM is ideal for Ram 1500 owners who want to unlock additional performance potential beyond factory limits. It is perfect for enthusiasts seeking custom tuning capabilities, professional tuners who require a flexible calibration platform, and anyone looking to enhance throttle response, towing performance, or overall engine efficiency without sacrificing reliability.
This product is not available for sale or use on pollution-controlled vehicles and may not comply with emissions regulations in certain regions. Please verify local laws before purchasing or installing this modified PCM.
DiabloSport makes handheld tuners and ECU tuning solutions aimed at unlocking additional performance and improving drivability for many late-model domestic trucks and muscle cars. Their devices and supported tuning ecosystem are commonly used to optimize engine and transmission calibrations after mods like intakes, exhaust, or gearing changes.
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
