For the people who say "my gauge is off" - how do you know? If you're comparing it to a MAP sensor read-out, how do you know the MAP sensor is accurate? MAP sensors have a number of issues, and will give different read-outs at different elevations. Additionally, the MAP sensor read-out will vary with the weather ("there's a high presssure front coming in..."), and they also vary in accuracy based on temperature and pressure. Here's another data point - some people were complaining about the boost number from my ECU+ product when using the GM 3-bar MAP sensor, so I the tested a customer's new-ish sensor and a brand new one. Results: brand new one was about 1 PSI low, and varied by about 1/2 PSI across a few trials. The almost-new one was 3 PSI low, and varied by as much as 5 PSI from trial to trial, especially around 20 PSI. (The ECU+ software was, of course, spot on, but it can't do anything to correct a screwed up MAP sensor.)

So then what is the correct and accurate device then?

Zeitronix calibrates for altitude.

If barometrics affect your map sensor with weather the same barometrics are affecting the air the car ingests so it makes no difference. It is working exactly as it should.
