I know I'm retarded but I honestly don't know... since I have swapped engines in my car and it will go very much faster now... my original gauges only register 110mph, if I get a gauge overlay that registers 145mph, what kind of changes will have to be made for it to be correct? Or can you even do that? Am I just stuck with the 110mph gauges or overlays? Thanks.

youd probably need a new cluster that is set up for those kinds of speeds then you get your overlays for that.
