The mountune Stage 1 upgrade delivers phenomenal performance for the Audi S3 (8V) with either manual or S Tronic transmissions.

Based on over a decade of tuning vehicles to pass OEM sign-off, the mountune Stage 1 offers the highest quality calibration, providing improved drivability, response and of course, a substantial increase in both power and torque, all vigorously durability tested to provide peace of mind that reliability is maintained - even when the power is increased to 360PS and torque is raised to 500Nm.

It also boasts enhanced vehicle functionality, can be used to monitor gauges via the OBD port, and also includes a performance meter as well.

A return to stock option is included, together with an anti-theft option.

The mountune Stage 1 is available in two versions to fully exploit both manual and S Tronic transmissions. The S Tronic version also includes a fully optimised transmission calibration option (you can choose this option above). This is programmed into the TCU (transmission control unit) by the SMARTflash app, which then allows it to maintain higher torque levels through the revised clutch pressure optimisation. Shifts are faster, giving harder and quicker acceleration through the gears, whatever level of performance your car has and the launch control benefits from a revised, more aggressive strategy.

For manual owners that don't want to fit an uprated clutch kit, the mountune Stage 1  calibration includes multiple selectable torque modes within the performance calibration as standard, so you can still safely run increased levels of performance without the fear of near instant clutch-slip.

Whilst not essential, it is recommended to achieve and maintain the quoted power figures under hard use, an aftermarket induction system should be used, like the mountune X3, which the Stage 1 calibration has been fully optimised for.

Please Note: Whilst every effort is made to provide calibration support for all known available base variants, due to the number in existence, there may occasionally be a delay in enabling support for your vehicle. Should this be the case, options to provide this support will be made available, or you will be offered a full refund until specific calibration for your vehicle can be provided.
