Tune Stage 3 Petrol

A stage 3 tune is considered by most to be a level that’s best invested in for the track. That’s because it can be very expensive. It usually involves upgrading the intercooler, cylinder head and inlet valves, head gasket, and spark plugs in additional to all stage 2 modifications.

This stage will require a car to be set up on a rolling road to optimise the fuel and timing and correct exhaust emissions. It is also at this stage that the stock turbo on a car might be upgraded, although this is recommended as the final modification to complete vehicle tuning.
