FabSpeed McLaren 600LT ExperTune Performance Software

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.      POWER GAINS - Stock Hardware 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 f
