hey

so I want to replace face of my gauges in my 06 lancer es. and to clarify im not actually replaces the gauges just the face i.e. the color of the numbers and lines on the speedometer. only thing is that the one im putting on goes to 150 mph rather than 130 like my current one. so my questions is...how do i adjust the speedometer. do i have to take it in or do i need to buy something to do it. or can i just go hands on in my engine and take care of business....any help would be greatly appreciated guys...

thanks
