Hey Max....and anyone else that can help me. I put some wheels and tires on my truck that are smaller than my stocks were, and I was wondering if there was any way to figure about where my rpm's are at when I am going down the highwy. I know a tac would tell me lol, but I dont have one, and not where I want all new gauges. The miata.net calculator tells the revs/mile, but is there a way to actually tell anything from that?
Also, is there a way to calibrate the speedo, rather than doing gears or a taller tire to get the speed back to where it should be? Was told you can do that, but not sure?
