i have an aem ems 30-1052 the older version, is the boost controler fonction in this work good, cause im am hesiting between buying a aem tru boost or the aem boost gauge digital, if the boost controller in the ecu work good i will only buy the aem digital gauge only ,cause is cheaper your opinion please, if y can use the ems i will do it

 

Aem controls boost just fine. you'll need a mac solenoid and the "d plug" to wire it all up. Don't waste your money on another boost controller
