I hope this is the right fourm for this. I did some searching but was unable to come up with any answer.

My question is what do you look at on the interceptor to see the boost PSI. Because the the supercharger inlet and the other one NEVER go past 10 at all and i used to read 15-20 vac crusing around and they never go much past -10. Let me know because im going nuts. Or do you hook up the factory one thru the Analog 1 or analog 2?

The interceptor gauge reads the boost by "manifold psi."

At cruising it should be around -10

 

What he said^ the stock gauge reads boost in psi and vacuum in inches of mercury but the interceptor does it all in psi
