Stage 1 DSG Software
DSG transmission performance software allows you to use the full potential of the engine, giving the 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 DSG software.
Revo DSG software can be run on a standard car and it complements our full Revo Stage 1 ECU software.
Stage 2 DSG Software
DSG transmission performance software allows you to use the full potential of the engine, giving the 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 DSG software.
The Revo DSG Stage 2 software is aimed at cars with more significant hardware modifications; exhausts and turbos and delivers an awesome experience when combined with our Stage3 ECU performance software, with a choice of 3200, 4000 or 4500rpm launch control and enhanced shift maps to suit vehicle set ups.
