    The DiabloSport Trinity is a maximum function programmer and display unit all in one. For gasoline-powered vehicles, the Trinity features pre-programmed levels for high octane fuel (91 or 93), or regular gas (87 octane) that will boost horsepower by up to 40, depending on vehicle model. If you have customized your vehicle with a cold-air intake, upgraded MAF sensor, or installed a custom-sized pulley wheel for a factory supercharger, the Trinity features 5 additional program levels that account for any or all of these modifications to give you higher, more extreme levels of performance. Diesel trucks will typically see an improvement of up to 60 horsepower and 100 foot-pounds of torque, and achieve 2-3 additional miles per gallon on the highway under normal driving conditions.

    The Trinity features a 320 x 240 pixel high-resolution color screen with 7 buttons on the right side for easy operation, and 5 LED lights that can be set to flash for pre-determined warnings or reminders. A Dragstrip timing feature allows you to clock quarter-mile, eighth-mile, zero-to-sixty, and zero-to-100 measurements based directly on speed and distance readings from the vehicle itself. Unlike other programmers, the Trinity will start the clock after racetrack style red-yellow-green lights flash, or the instant you press the accelerator pedal. The Trinity also allows you to modify engine RPM idle speed, rev limits, transmission shift points and firmness levels, and your vehicle’s built-in speed limiter.

    Founded in Florida in 2000, DiabloSport® established itself in the world of automotive performance products by pioneering Electronic Engine Control Level 5 (EEC-V) software cable of delivering speed necessary to run a modern master vehicle computer control system equipped with extra limbs such as airbags, traction control, ABS, air suspension and more. Today, Diablosport has built their knowledgebase into a full line of vehicle performance tuners that increase fuel economy, power, and torque – with the ability to be custom programmed to a specific make and model to the highest level. From under hood control modules that increase horsepower and fuel economy in stock vehicles to tuners with abilities to create 800+ horsepower in racetrack modified applications, each Diablosport product offers value with state-of-the-art technology. All Diablosport products are fully engineered, tested, and manufactured in the United States.

    Does not work for an 04 Ram hemi have to set it up for a 05 hemi. Other than that it works great! Bought it mostly to help fuel mileage. Comes preset with a gas saver tune but i did the performance tune and that even helped. Went from 10mpg to about 13.

    Good And Bad
    Looks nice works good if you know how to use it. Other than that the buttons are cheap and you have to keep taping them if you don't push them hard. Other than that give power and torque for days Judy would advise getting a cai and throttle body and bigger headers to see a big gain.
