Its not ERG though and that's what effects the running of the engine! I had an escort Mexico mk2 and that drive sublimely compared to modern engined cars. Modern engined cars have engines that are designed to run hot so that the ERG emissions can be fed through the engine, this keeps the engine temp down so all those who remove/blank there ERG valve because lets face it they want it to run better are in fact destroying their engine as its running way to hot. Only way to keep it lower is to over-fuel it with all the issues that brings to the mix. Especially if it's turbocharged.
