DiabloSport inTune and Trinity 2014-15 V6 GM Truck Tuning Out Now!

DiabloSport is proud to release the newest tuning sets for their popular inTune and Trinity programmers. The new tuning is now available for 2014-15 GM Trucks with the 4.3L V6 and is sure to give your truck the extra horsepower and torque you have been looking for without even opening the hood.

Official Release:

The inTune and Trinity performance programmers for the 4.3L V6 Chevy Silverado and GMC Sierra overhaul drivability in just a few minutes. All you have to do is plug into the OBD-II port on your truck (located under the dash) and you can add horsepower and torque without even popping the hood!

Improved Throttle, Better Drivability!

We made several dyno pulls on our 4.3L Silverado development vehicle to ensure the highest possible power gains. Running 93 octane gasoline, we saw peak gains of 10 Rear Wheel horsepower, and 14 Ft.Lbs of torque (20 Ft.Lbs at low RPM). We went on to optimize drivability by enhancing throttle response, cleaning up transmission shifting, and amplifying the factory tow/haul mode. Many 4.3L Silverado and Sierra trucks have a factory equipped “Flex Fuel” option, which means they can run any blend of fuel from E85 to regular 87 octane gasoline, and our calibrations department developed tunes that maximize performance regardless of what mix of fuel you are running. We filled up the tank with E85 and got a huge performance boost over stock: 20 horsepower and 24 Ft.Lbs of torque! Other options available in our inTune and Trinity programmers include: gear ratio, tire size, fueling, timing, idle RPM, rev limiter, and the speed limiter. They even support CMR custom tuning that can calibrate you truck for more aggressive aftermarket performance modifications. With our tunes and adjustable options at your fingertips you can take full control of your truck like never before!

Seven Pre-Loaded Performance Tunes & Adjust Stock Setting

The tune selections for the ’14-‘15 4.3L Silverado and Sierra depend on the type of fuel you want to put in the tank. For the biggest power gains we recommend running E85 fuel (for flex fuel equipped trucks), or regular 93 octane. Be sure to pick the tune based on what fuel you have in the tank.

91/93 Octane Flex Fuel Tune
+10 HP | +14 TQ Gains on 91/93 octane fuel
+20 HP | +24 TQ Gains on E85 Fuel
This tune optimizes your truck’s performance for 91 or 93 octane gasoline. If the truck is equipped with a factory flex fuel option, you can get even more power by running E85! The tune works with factory flex fuel equipment and allows you to run a blend of 93 octane and E85 and achieve peak results for your mixture. Note: Vehicles that do not have Flex Fuel factory options will need to run minimum 91 octane with this tune for power gains.

87 Octane Flex Fuel Tune
+5 HP | +8 TQ Gains on 87 octane fuel
+20 HP | +24 TQ Gains on E85 Fuel
This tune optimizes your truck’s performance for 87 octane gasoline. If the truck is equipped with a factory flex fuel option, you can get even more power by running E85! The tune works with factory flex fuel equipment and allows you to run a blend of 87 octane and E85 and achieve peak results for your mixture. Note: Power gains may vary based on the mix of E85 fuel and 87 octane gasoline in your gas tank

Mileage Booster Tune | +2 MPG
If you’re after fuel economy this tune is for you. Our mileage booster technology allows you to pick up an average of 2 MPG on your stock truck without adding a power boost. It’s perfect for long road trips or commutes!

Firm Shift Transmission Tune
The Firm Shift tune greatly improves the 6-speed transmission for a better feel! This tune is recommended for drivers who are looking for a performance shift, but do not want it to be too aggressive for daily driving

Hard Shift Transmission Tune
The Hard Shift transmission tune maximizes your 6 speed transmissions shifting for those who prefer an aggressive shift feel

Factory HP Tune/Factory Transmission tune
This tune uses the truck’s factory calibration, but allows for modifications to the tune to suit your own needs.
