This Tune Helps You Tow With Confidence Every Time

If you're putting serious miles on your Ford F250 or F350 and regularly towing heavy loads, this Heavy Tow Tune is exactly what your truck needs. Built for the hard-working driver who pulls trailers, equipment, or heavy service rigs, this custom tune delivers noticeable performance gains without pushing your truck too far. With a healthy bump of +30 RWHP and +66 ft-lbs of torque, you’ll feel your rig move quicker off the line, lug better in the right gear, and shift smoother when under load. It’s designed to tow up to 8,000 lbs GVW while keeping things safe for your emissions system and your drivetrain. Whether you're climbing steep grades or maneuvering through city traffic, this tune gives you the confidence to throttle back without sacrificing power. It’s perfect for fleet owners, contractors, or anyone who logs thousands of heavy-duty towing miles each year. You get all of this while keeping the factory turbo brake and reliability you count on day in and day out.

Calibrated For Control And Built For Heavy Loads

This tune is more than just added power, it’s a carefully engineered calibration that balances performance with reliability for your 2011-2012 6.7L Powerstroke. With over 100 adjustments made to the stock programming, it optimizes air-fuel ratios to limit soot production while boosting usable torque across the RPM range. SMART EGT Control actively manages exhaust gas temperatures to ensure safe towing under sustained load. The tune is also emissions intact, so you don't remove any emissions equipment, making it a safe choice for trucks that stay road-legal. Factory turbo braking is retained, allowing full downhill control while towing heavy loads. Whether you’re using this tune to tow equipment, service trailers, or for daily fleet operations, it provides smoother throttle response and keeps your truck in the right gear without unnecessary shifting. Paired with optional TCM tuning, this setup gives you even more refined shifting, torque converter control, and improved drivability when under pressure.
