I took a look at your last post from 2014. So tell me, do you still believe this?

So math: 4÷25.4 will give us what percent difference it is between a 1 inch hose and a boost line. So 4÷25.4=0.1574 or 15.74%. So your boost gauge is 84% (100%-15.74%) smaller than what PSI reading are suppose to be measured in (a 1inch hose).
Games you are too funny. I wonder how long you spent looking for this. You won't read how a turbo works but you will spend hours looking for dirt. Reread the post. I wrote this in the correct context of what the poster was asking.

As for the fuel psi issue. It does sound to me like the lift pump is bad. Another thing I have seen is using the wrong fuel line from the tank. The lift pump will actually draw enough suction to collapse a weak fuel line. Last I saw this a guy was running 1/2" heater hose instead of fuel injection rated hose. Anyways, just another area to check.
