Even with using the HPTuners speedo fields, the GPS reads 72.xMPH when the scanner says 70MPH. I used to know what to divide by what and apply where, and I know there's a thread around here somewhere but I've not been able to locate it. Unfortunately I'm a little OCD about this crap

So 70/72=.97, so do I multiple .97 by the VSS pulses & Trans revs to get the new values? I seem to recall it involved the tire height & final drive values, though. Can anyone confirm?
