McLaren 600LT ECU Tune
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.
There is a copious amount of power waiting to be had that McLaren has hidden from you. The 600LT responds incredibly well to a tune and rewards you by taking the performance to a whole new level. Our tune brings the turbos to life with a vengeance, the car reaches boost immediately and pulls hard and consistently throughout the power band. The response and power delivery is outstanding, this is a true driving machine.
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.
