I got one for ya.....last night at the track I'm trying to overlay my data log w/ no success. Then I notice that on the VE table I'm reading a crap load of vac (KPA was 1), but my gauge is showing 10". I decide to give'er a little thottle and the indicator stayed along the bottom of the map changing with the RPM, but not the KPA. Just for giggles I went over the the timing map and it was working fine. Any idea's
