For Stage 2+ and higher tunes TVS always recommend at least RON98 fuel, but our tunes are available for lower and higher fuel grades as well.

For Stage 2+ and higher tunes at least an upgraded air intake system and downpipe are required. An upgraded intake air system improves performance over the factory one by increasing the mass air flow through the system and thereby improving power, torque and throttle response.

For Stage 2+ and higher tunes at least an upgraded air intake system and downpipe are required. A downpipe normally eliminates unnecessary factory restrictions and creates an ideal flow path to maximize exhaust gas flow and thereby improved performance.

For high performance applications TVS always recommend an upgraded intercooler. In order to decrease charge air temperatures and being capable of supporting power levels far beyond that of the OEM intercooler.

Upgraded catback exhaust systems normally uses larger piping and less restrictions compared to the factory exhaust for increased performance. Especially for high peprformance applications TVS always recommend an upgraded exhaust system.

Next to increased performance, TVS enhanced engine cooling and oil temperature management keeps your engine within optimal and safe temperature limits for maximum performance, durability and realibility!

Besides increasing performance, TVS is always focussing on several parameters related to fuel economy, especially while city driving or highway cruising. Depending on several factors such as driving style and fuel quality, improved fuel economy may be achieved.

TVS is able to adjust or remove the vehicle speed limiter from your vehicle to any desired value.

For Stage 3 and higher tunes a decent upgrade turbo- or supercharger kit is required. Due to our knowledge, experience and specialism in calibrating high power applications, TVS is nowadays able to create custom software for almost every turbo- and supercharger upgrade.

When installing a decat downpipe it is important to carefully recalibrate the ECU software and optionally disable the function of the second lambda sensor located after the removed catalyst.

TVS is able to recalibrate upgraded injectors properly within the ECU software for high performance vehicles for which factory injectors are not sufficient.
