Question 06 Cobalt SS/SC Mechanical Boost HELP!

So i followed previous threads and put in a mechanical boost gauge just as they did heres a link to it.
https://www.cobaltss.net/forums/how-...rite-up-15721/
So i did all of this but my boost gauge reads 20 Vacuum, however i want it to read out on the PSI Boost side so i know how many lbs of boost i am getting to the engine. If anyone looks at that thread i followed it exactly so thats where I'm at, is there anything i can do to make this work?

You should be reading vacuum until you give it a decent bit of gas. At idle it should read somewhere around 20 Vac.

If your wondering why it's not building boost while stopped maybe your not revving high enough? Do a full pull through 2nd and 3rd.. See what it reads.. If nothing in the normal range theres a leak somewhere..
