There are a lot of options when it comes to the modification of Ford Endeavour's 2.5 L engine. The most exclusive modification would be ECU remapping, which can boost the overall power of the vehicle by 35% from the stock values in the stage 1. Throttle response is further improved while by using some performance parts, the values can be taken by up to 50-70% in the higher stage maps. These maps also lead to a higher refinement of the engine, thereby bringing in 20% more fuel efficiency in some cases. You can use aftermarket exhaust system for better and race inspired feel.
