I've searched already and I found nothing on the subject.

As far as I know, a stock D16 map sensor reads about 10 PSI (give or take .5). If I'm correct, this is a total of 24.7 including atmospheric pressure at sea level. if I go to a higher altitude where atmospheric pressure is 11.7, will the stock map sensor be capable of reading 13 PSi for a total of 24.7?

In simpler terms...does the stock map sensor max out at 10 PSI regardless of elevation or does it max out when it reads a TOTAL of 24.7 PSI?

 

Total. The MAP sensor's voltage reports absolute pressures.

 

If you want to tune for higher boost levels the stock map won't read above 11 PSI, but you can tune for as much as you want. the map will just read the 11 PSI column and stay there even if your actual boost is a lot higher. Get it?

So it'll read lower voltage when you're at higher alitude? I just wanna confirm this.
