Stage 3, Haute couture preparation

To continue to increase the horsepower of your vehicle during a stage 3 engine reprogramming, the demand for fuel is much greater than that of an original vehicle. A standard fuel pump (high-pressure or low-pressure) can quickly prove insufficient to ensure optimum fuel supply to the engine when it is running at full load. It is therefore essential to replace the original pump with a high-performance fuel pump capable of delivering sufficient flow to meet the engine's needs.

A complete exhaust system is an effective way of improving your vehicle's performance during Stage 3 preparation. It reduces back pressure and optimises exhaust gas evacuation, resulting in increased power and torque. During a Stage 3, we recommend changing the diameter of the line pipe to improve gas evacuation and enhance performance.

Installing performance parts is essential, but without custom engine mapping, the effectiveness of these improvements is limited.

At Shiftech, we excel in the development of customised power dyno maps. Our experts use state-of-the-art equipment to adjust and optimise each vehicle's settings, ensuring perfect harmony between the performance parts and the engine.

This approach guarantees not only an increase in performance, but also the reliability and durability of the vehicle, turning each modification into a significant and measured improvement.
