i just bought a aem ems from a evom member that has no sensors with it. if i want to run 30psi or more should i get the 5-bar map sensor? also what is the part number so i can have the ems control the boost or should i get the new tru boost gauge?

 

1> yes you will need the 5 bar map sensor and a air intake tempature sensor. To go without the MAF.

You can use a GM or aem boost solenoid with the ems to control boost But it didn't work with my car so I just use 2 manual boost controllers race/pump gas. Haven't heard anything good or bad about the tru boost( go check on the aem electronics forum and see if people are havein success with it)
