And yes, Absolute pressure and Gauge pressure are generally what it is called.

Yes 8psi is reasonably low, but for all practical purposes running 15psi in a stock Tc motor is asking for trouble. I just did not know if there was a reason for upsizing a gauge. I know in welding applications it is recomended that you go 200% on the gauge to what you expect to be working with .

From personal experience racing all over the country, in Denver (about 85kpa atmospheric pressure), we were seeing about 5-8psi less boost compared to when the turbo was maxed out at sea level.
The last point is exactly what I was trying to convey Tony, but keeping it VERY simple under the K.I.S.S. laws, however I did not want to breach dyno figures into the equation because that spins off a whole different ball of wax and even more heated debate.

thats like arguing with gravity, you can't do it.

right but we're not talking about quantum mechanics or such we're talking about pressure. which is accepted..... there isn't much debate over pressure....
