In the workshop this week our first stage 2 upgrade on the newer Audi S4 B9 turbo. This vehicle has a Wagner up-rated inter-cooler Milltek de-cat exhaust section and high flow carbon intake system.
Ecu remapping at the moment is a bench flash but no opening of the ECU just a set of cables to enable us to read and write to the ECU .
Tuning was taken care of by one of our tuning partners Avon Tuning and after rolling road testing and optimisation a respectable 430 bhp was achieved on our version 1 stage 2 software transforming the drive of the car with the sort of performance you would expect . We expect more development in time and further improvements to be made . We are also able to offer a stage 1 tune with no hardware modifications.
