PSC Tow Performance Package (2015-2019 6.7L powerstroke)

6.7L Powerstroke Tow Performance & Reliability Package

(2015–2019 Ford Super Duty)

This package is engineered specifically for towing performance on the 2015–2019 6.7L Powerstroke platform. If your truck spends its life pulling trailers, equipment, campers, or heavy loads, this setup is built to deliver strong low-RPM torque, controlled EGTs, and long-term reliability—exactly where towing trucks need it most.

Every component in this package is chosen to improve real-world towing performance, not just unloaded acceleration. The goal is simple: tow heavier, stay cooler, and protect your engine and fuel system while doing it.

What’s Included in This Tow Performance Package:

✅ Stage 1 KC Whistler Turbo

(2015–2019 6.7L Powerstroke)

The KC Whistler turbo is an ideal towing upgrade for the later-model 6.7L, designed to:

• Spool quickly at low RPM

• Improve exhaust flow and efficiency

• Reduce EGTs during sustained towing

• Deliver smooth, predictable power

Unlike oversized performance turbos, the Whistler is tuned for low-end and mid-range torque, making it perfect for trucks that spend time under load rather than wide-open throttle.

✅ S&S® CP4 to DCR Fuel Pump Conversion

(2015–2019 6.7L Powerstroke)

A must-have reliability upgrade for any 6.7L that tows.

The factory CP4 pump remains a known failure point that can contaminate the entire fuel system. The S&S DCR conversion:

• Eliminates CP4 failure risk

• Provides consistent fuel pressure under load

• Protects injectors and fuel rails

• Supports towing and future performance upgrades

This upgrade provides peace of mind, especially when towing long distances or heavy loads.

✅ Cold Side Intercooler Pipe

(2015–2019 6.7L Powerstroke)

The factory cold-side pipe can become a restriction under sustained boost. This upgraded pipe:

• Improves airflow efficiency

• Eliminates the unreliable factory cold side pipe 

• Lowers intake air temperatures

• Improves throttle response while towing

This ensures compressed air from the turbo reaches the engine efficiently—critical for maintaining power and safe operating temperatures under load.

Why This Tow Package Works

✔ Designed for low-RPM and mid-range towing power
✔ Helps control EGTs on long grades
✔ Eliminates the CP4 fuel system risk
✔ Improves airflow from turbo to intake
✔ Maintains smooth drivability and towing manners
✔ Built for trucks that work—not race

Who This Package Is For

This tow performance package is ideal for:

• 2015–2019 6.7L Powerstroke owners

• Trucks that tow regularly

• Owners focused on reliability and heat management

• Daily-driven work trucks

• Customers planning future upgrades safely

❌ Not intended for max-HP or race-only builds
✅ Built for dependable, confident towing

What You’ll Notice When Towing

• Faster turbo response when pulling from a stop

• Lower EGTs on long hills and grades

• More consistent power delivery under load

• Reduced stress on the fuel system

• Improved towing confidence and drivability

The Bottom Line

If your 2015–2019 6.7L Powerstroke earns its keep by towing, this is the setup it needs. The combination of the KC Whistler turbo, S&S DCR fuel pump conversion, and upgraded cold-side intercooler piping delivers a balanced tow-focused build that runs cooler, pulls stronger, and protects your engine long-term.

This is how you build a 6.7L that tows hard, stays cool, and lasts. 💪
