Bully Dog offers the GT Platinum and BDX flash programmers for gas and diesel applications, while the Hypertech Spectrum covers a wide range of truck and SUV platforms.

For throttle response, we stock Sprint Booster and Banks Pedal Monster controllers that eliminate factory throttle delay on F-150, Ram, Silverado, Sierra, Wrangler, Tacoma, Tundra, and Titan. Need a speedo calibrator after a lift kit or bigger tires? We carry Hypertech and SCT speedo calibrators for Ford, Ram, GM, and Toyota trucks. For AFM and DFM management on GM trucks, the Range Technology AFM disabler and DFM Inline Module eliminate cylinder deactivation without reprogramming your ECU. Pair your tuner with a cold air intake from Air Intake Systems and an aftermarket Exhaust system for maximum power gains. Monitor your engine vitals with Gauges and A-pillar pods from AutoMeter.

Frequently Asked Questions

Do performance tuners actually increase horsepower and torque on trucks?

Performance tuners recalibrate your engine's air-fuel ratio, ignition timing, and transmission shift points to extract more horsepower and torque from your existing engine. Gains vary by platform — gas trucks typically see 15-40 HP increases, while diesel trucks with tuners like the Banks Derringer can gain 50-100+ HP depending on the tune level and supporting modifications like a cold air intake and exhaust system.

Does installing a tuner or programmer void your truck warranty?

Dealerships can detect aftermarket tuning through your ECU's flash history, which may affect warranty coverage on powertrain-related claims. However, the Magnuson-Moss Warranty Act requires the dealer to prove the tuner caused the specific failure — they cannot blanket-deny all coverage. Throttle response controllers like Sprint Booster and Pedal Monster do not modify your ECU and leave no trace, making them a warranty-safe alternative for improved throttle feel.

Which is the best truck tuner brand: SCT, Bully Dog, or Banks Power?

SCT is the strongest choice for Ford gas and diesel trucks with the X4 and Livewire TS offering deep custom tuning and data logging. Bully Dog's GT Platinum is a solid all-around option across Ford, GM, and Ram platforms. Banks Power focuses on diesel performance with the Derringer tuner — delivering calibrated, dyno-tested power gains paired with iDash monitoring. The best brand depends on your truck platform and whether you prioritize custom tuning flexibility or calibrated diesel-specific power.

What does an AFM or DFM disabler do on a GM truck?

Active Fuel Management and Dynamic Fuel Management shut down cylinders during light-load driving to save fuel on GM 5.3L and 6.2L V8 engines. While this improves fuel economy slightly, it often causes rough idle, oil consumption, and lifter wear over time. An AFM or DFM disabler like the Range Technology module plugs into your OBD-II port and keeps all eight cylinders firing at all times — without reprogramming your ECU or triggering check engine lights.

Do you need a speedometer calibrator after installing bigger tires or a lift kit?

Larger tires increase the rolling circumference of each wheel rotation, which causes your speedometer to read slower than your actual speed. A speedo calibrator after a lift kit or tire upgrade corrects the speedometer, odometer, and transmission shift points to match your new tire diameter. This is especially important for trucks with electronic stability control and traction systems that rely on accurate wheel speed data.

What is the difference between a performance tuner and a throttle response controller?

A performance tuner reprograms your engine's ECU to change air-fuel ratios, ignition timing, rev limits, and transmission shift points — increasing actual horsepower and torque output. A throttle response controller like Sprint Booster or Banks Pedal Monster does not add horsepower — it reduces the electronic delay between pressing the gas pedal and the throttle body opening, making acceleration feel sharper and more immediate. Many truck owners use both together for maximum driving improvement.
