2021 Ram 2500 | S400 + Built 68RFE + CCV Switch Tuning 🔥

This 2021 Ram 2500 is running a full custom tuning package designed around an S400 turbo and a built 68RFE transmission. Every tune is calibrated specifically for the truck’s setup to deliver smooth drivability, quicker response, and reliable power.

One of the standout features is our CCV Switch Applied Tuning, which uses the factory DEF gauge to select your power level on the fly. Whatever position the DEF gauge is pointing to is the tune level the truck is running—no extra switches or aftermarket controllers required.

This truck also features our Steering Wheel Control Fuel Management, allowing the driver to adjust fueling characteristics directly from the factory cruise control buttons while driving. Everything is integrated into a single tune file for a clean OEM-style experience.

For the built 68RFE, we raise the shift points, increase line pressure where needed, optimize torque converter lockup, and command wide-open-throttle shifts around 3,500 RPM to take full advantage of the S400’s power band.

Whether you’re running a stock VGT, modified VGT, or an S400-based setup, we build every calibration around your exact combination—not a one-size-fits-all file.

24 L5P Duramax E42 — 200HP Rumble Tune

This 2024 L5P came back in for a change in sound. We originally set the customer up with a hiss tune, but this time he wanted a deeper, more aggressive exhaust note, so we switched it over to our rumble tune.

Engine + transmission tuning completed through HP Tuners. Available remotely or in person.

Engine:
• 200HP tune
• Rumble idle
• Aggressive low boost fueling
• 4,400 RPM hard cut limiter
• 40 PSI peak boost at WOT, tapering to 35 PSI
• Calibrated to keep EGTs in a safe range while still making strong power

Transmission:
• Increased line pressure
• Firmer shifts
• Firmer torque converter lockup

Whether you want hiss or rumble, we can set the truck up around the sound, power, and drivability you’re looking for.

Remote tuning available nationwide or bring the truck to us for in-person tuning.
