Hello, I'm wanting to buy some simple and reasonably priced speedometer for tractor pulling with a MPH limit. I have been looking at GPS stuff but I'm wandering if any of you all have something that will work either on measuring ground speed or GPS or what your opinions are on how to accomplish...
From central Missouri, I have a 07 classic ccsb dmax, DE cat back exhaust, ppe air box mod, PCV rerouted, & waiting for warrant to go out to start modifying
