You left out all the important information. What's your setup?

I'd imagine it's supposed to be more than 3-4 psi. Your mechanical gauge is probably correct. Could verify it by installing another gauge if you like.

I would guess that a pulley with 3.1 would be too much boost
for your set up. My A&A kit had a 3.6 pulley new. I had 7 lb boost,I went to a 3.48 pulley and went to 12 lb boost, with meth. I would
guess you will have more boost.
