Mercedes Sprinter ECU Tune 2011-2023 (Up to 406 lb-ft) | KermaTDI

Sprinter ECU Tune for 2011-2023 Mercedes-Benz Sprinter

The KermaTDI Sprinter ECU Tune adds up to 406 lb-ft of torque to 2011-2023 Mercedes-Benz Sprinter diesel vans. It fills in the low and mid-range torque a loaded Sprinter needs, cuts turbo lag and sharpens throttle response, with no check engine lights or dealer flags.

Built for Heavy, Hard-Working Vans

Most Sprinters run heavy every day, whether as upfitted work vans, fleet vehicles or full camper builds. Stock calibrations feel flat under that load. Our tune gives your van:

• Up to 406 lb-ft of torque, with the biggest gains low in the rev range where you pull away from stops and climb grades
• About 235 whp, roughly 25% over stock
• Less turbo lag and faster response when merging, passing or towing
• Altitude-tested calibration that performs from sea level to 12,000 feet
• No check engine lights or dealer flags

Fitment

• 2011-2022 Mercedes-Benz Sprinter, 4-cylinder and 6-cylinder diesel
• 2023 Mercedes-Benz Sprinter, 6-cylinder diesel
