Truck Tuning

Drive further. Tow harder. Never look back.

Power, torque, & efficiency where it matters most.

Redline’s truck tuning service is built for serious operators who rely on their machines day in, day out. Whether you’re running line-haul, local delivery, or heavy haulage, our ECU remaps deliver smoother power, stronger torque, and better fuel economy — all while staying within safe operating limits for your engine and drivetrain.

Smarter tuning for real-world work

Every tune is written in-house and tailored to your specific make, model, and use case. We don’t use generic files or overseas maps — each truck is tuned to perform at its best across the conditions it actually faces on New Zealand roads.

  • Up to 20% better fuel economy (depending on load and route)
  • Improved pulling power for hills and heavy loads
  • Reduced gear changes and smoother acceleration
  • Lower emissions and cleaner running engines
  • Safer, more efficient towing and hauling
Safe, tested, proven

All tuning work is backed by diagnostic testing and post-install validation. Original ECU files are always stored, so your truck can be reverted to stock at any time if needed.
