Thanks gents! I sort of understand it now. You are correct that my gauge reads from 0 - 30"...I wanted a full face gauge because the full swing is more sensitive than the small section that is used on a boost/vac gauge.
So basically the best driving technique is accelerating at 5" (or a little lower) and up-shifting at no more than 2500rpm? Obviously tweaking for nuances of the car/diver as I track MPG over tanks of gas...
Thanks for all the insights so far.
