    Looking for quicker shifts, improved torque management, and enhanced overall drivability from your 2011-2014 5-speed automatic?

    N2 Speed has the answer- a pre-programmed transmission control module designed to improve the performance and responsiveness of vehicles equipped with the NAG1 (W5A580 / Mercedes 722.6) 5-speed automatic transmission.

    The cost is $499.99.

    Sounds like a great addition. I envy the old 3.5 liter DOHC with individual exhaust ports.Great for the naturally-aspirated crowd. The monopoprt made me forget about a 3.6 AWD Challenger and instead go for a used Hellcat.
