Sport Tune

Peak Horsepower & Torque for the Ultimate Thrill-Seeker

• 595 HP & 1180 ft-lbs of torque
• +150 RWHP + 270 ft-lbs
• Fastest possible acceleration
• Firm shifting
• No dead pedal
• Not recommended for towing - without proper gauges and equipment

If you’re looking for the most aggressive performance tune available, the Sport Tune is built to give you the most horsepower and torque possible for heart-racing acceleration. However, it’s not ideal for towing or everyday use — only for those who want raw power and don’t mind a firmer, more aggressive shift.

Street Tune

• 545 HP & 1090 ft-lbs of torque
• +100 RWHP + 180 ft-lbs
• No dead pedal feeling
• Most power & torque you can add while maintaining OEM levels of reliability
• Truck feels lighter
• Retains factory turbo-braking functionality

The Street Tune is designed for those who want more power without compromising reliability. It offers a substantial horsepower boost, while maintaining a smooth and consistent power curve that makes everyday driving fun and effortless. Perfect for those who want the best of both worlds: enhanced performance without sacrificing drivability.

Light Tow Tune

• 525 HP & 1054 ft-lbs of torque
• +80 RWHP +144 ft-lbs
• Smooth power curve
• Air-Fuel Ratio limits built-in
• Designed to tow <8,000 lbs.
• Factory turbo brake retains complete functionality

The Light Tow Tune is ideal for those who need extra towing power, but don’t plan on hauling massive loads. It’s perfect for light to moderate towing, like smaller trailers or boats, and ensures you can accelerate quickly without stressing the engine. With SMART EGT Control and power curve optimizations, your truck will tow effortlessly while keeping everything running smoothly.

Heavy Tow Tune

• 485 HP & 982 ft-lbs of torque
• +40 RWHP + 72 ft-lbs
• Increase power, not EGTs 
• Air-Fuel Ratio limits built-in
• Designed to tow up to GVW
• Factory turbo brake retains complete functionality

The Heavy Tow Tune is tailored for those who regularly haul large trailers or equipment. This tune increases power without pushing EGTs into unsafe levels, ensuring your engine runs efficiently and safely under heavy towing conditions. It also offers more usable power in all driving scenarios, helping you manage large loads with ease.

Optimized Stock Tune

Slight Revisions to Factory Calibration for Basic Performance

• Slight change to stock calibration
• No increase of peak power
• Great for when someone else drives your truck

The Optimized Stock Tune is perfect if you want a slight revision to your factory settings, but don’t need the full performance boost. It’s often used for troubleshooting or for when others need to drive your truck, providing a safe, stock-level experience with minor adjustments for better drivability.
