All modern vehicles have a sophisticated ECU (Engine Control Unit) that controls the performance of every component. The ECU is programmed by the manufacturer to produce a certain amount of power based on:
- Environment
- Emissions
- Fuel Quality
- Unique Country Specifications
Your engine, whether petrol or diesel, is likely to be restricted by the manufacturer or model of your vehicle. In many cases, there is a lot of untapped power to be released and using a TDI-Tuning Box will do this safely.
