The Revo Performance Stage 1 DL501 S-Tronic Gearbox Software has been carefully calibrated to work with our Revo performance engine software. Revo S-Tronic transmission performance software allows you to use the full potential of the engine, optimising the launch control, shift and torque limiter functions, giving control back to the driver. Hold onto the gear through that sweeping corner without the worry of the transmission shifting up and throwing out the balance of the car, have no worries about using full throttle and having the car jump about whilst shifting down for you… get back in full control with Revo S-Tronic software.
