    • Renntech X5 M dyno tune and 1/4 mile results = 518 all wheel horsepower and 12.2@111.91

      Renntech seems to be spreading to all platforms and that is a good thing. Increased tuner competition should bring out the best. We received this graph showing dyno results for the Renntech S63B44 ECU tune. The car puts down an eye popping 518 to the wheels on an all wheel drive Mustang dyno along with 497 all wheel torque. There is no baseline unfortunately for which to compare the gains from. The car did run 12.7@109 stock and with the tune managed 12.2 and almost 112 miles per hour in 87 degree conditions on just 91 octane pump gas.

        It is HARD to make that much power on an AWD Mustang Dyne! If only this drivetrain was in something lighter.....

        Yes, it seems RENNtech team have some nice decent gain on the X5 M. But, not sure if mentioned person Jeff or Evo company have much involvement on their new RENNtech X5 M inhouse calibrations Click here to enlarge.

        That kind of power on a Mustang Dyno is absolutely no easy feat. I haven't even seen a supercharged S65 hit these numbers on this type of dyno.

        It is a lot of power or a Mustang but a supercharged S65 with some higher boost should easily be breaking the 500's.

        Yes, I think what was said though is that Jeff is no longer involved with Renntech.
