What does ECM tuning mean?

ECM tuning is the process of fine tuning the software program that controls your engine fuel management system, without having to replace any part.  The result: more power, greater response and lower fuel consumption. What’s more, fine tuning an ECM has no negative impact on exhaust emissions or engine life.

We can increase the power of your engine by up to 30%. In 75% of the cases, even with a Performance tuning, you will still save on fuel. What’s more, optimal tuning of your engine will reduce your maintenance cost, since an engine with better combustion is a cleaner engine
