I don't know what your'e looking for..we use a 10 year old TAG unit that shows DA hum baro temp. A beer cruise with a smart phone at Brainerd showed it to be within a 120 DA feet of the average of 31 different devices. I can't tune 120 DA ft. Cheap and accurate. FYI



It doesnt matter if its off by 120ft just as long as
its always off 120ft.... you use that one unit on your
car ONLY.....
Bill I cant say weather the VP is better or not...
I've always used the DA on my unit(its about 10 years
old now) but I've always been VERY HAPPY with it and
its predictions to what the car will run... mine is
within a few thousandths, which is closer than you
need to dial... if it says I should run a 9.009 I
put .01 on the window but if its a .005 I go with
.00... its that close and the car is also
