The DiabloSport Pulsar LT and Trinity 2 MX kit combines inline performance control with full-color digital monitoring for 2019-2022 Silverado and Sierra trucks. The Pulsar LT connects inline to the factory PCM and adjusts throttle response, tire size, TPMS settings, axle ratio, and the speed limiter without flash tuning or PCM removal, and it also disables AFM/DFM and Auto Start/Stop. Adjustments are made through the factory steering wheel controls while parked or driving. The Trinity 2 MX adds a five-inch full-color touchscreen for customizable gauges, performance tests, high-speed datalogging, DTC reading and clearing, and expansion through the EAS accessory system, and the kit includes an application-specific pillar mount.
