    • McLaren 600LT baseline, 91 octane, and MS109 tune results by Dyno Spectrum

      Dyno Spectrum is putting their McLaren map switching to work on this 600LT which gets a 91 octane tune file as well as a MS109 race gas tune file. The owner can switch on the fly and of course has more slots available should he want a valet tune or maybe a nitrous file.


      Dyno Spectrum provided a baseline, 91 octane, and race gas overlay from the World Motorsports Mustang dynamometer:


      Very strong gains with the 91 octane tune picking up over 100 wheel horsepower and the MS109 tune clearing 700 horsepower to the wheels.

      The 600LT goes from fast to bonkers with some quality custom software. You will also notice the majority of the gains come up top making for a much stronger top end.

      It would be interesting to see the 1/4 mile trap speed now.
