  • 2019 - 2020 McLaren 600LT / 620R

Achieve maximum power gains (~80+ whp & 80 ft-lbs) without sacrificing drivability or reliability. Maps are available for completely stock cars, or for cars equipped with Sport Cats, Catbypass Pipes, X-Pipe Exhausts, upgraded turbos, and more.

You wouldn't believe all the power that's waiting to be unlocked in your 600LT. We've had ample time with a 600LT on our in-house Dynojet to unlock extra power on both stock vehicles and optimize performance with Fabspeed exhaust components. Once we receive your ECU, our tuner bench flashes it with the upgraded ECU map and we return it to you for easy re-installation; no modifications to the vehicle are necessary.

  • Stock = 533 whp / 506 ft-lbs
  • Tuned = 582 whp / 506 ft-lbs
  • Maximum gains of over 80+ whp at 5600 RPM and 80 ft-lbs of torque at 5000 RPM
POWER GAINS (With Fabspeed Catalytic Converters)
  • Stock = 533 whp / 506 ft-lbs
  • Tuned = 607 whp / 615 ft-lbs
  • Maximum gains of over 100 whp at 5600 RPM and 105 ft-lbs of torque at 3750 RPM
  • This is not a physical/shipped product.  This upgrade requires you to send us your ECU for re-programming. You will be emailed a download link with detailed instructions after adding this to your cart and checking out.
  • While a vehicle equipped with bolt-on upgrades will experience maximum gains as a result of the increased efficiency of the engine, great power gains can be made on a completely stock vehicle!  
  • You must fill out and include a copy of the ECU Information form along with your ECU upon sending it in. Please contact us if you need to send the form in any other manner.
  • Fabspeed Motorsport saves your stock/factory ECU settings so that you can revert your vehicle back to stock settings at any time.
  • Special requests and tune file upgrades may be subject to additional fees.
