AEM will control BOOST, but how?
 

I am looking at getting the AEM, I read that the ECU will control boost and read even control boost in each gear.

Cool, But how? Is it an add on control box? Is it included?

I just want to know if I should sell my beloved Greddy Profec-B.

Thanks, Jeff

It's included. Secondary computers typically piggy-back onto the stock ECU because the ECU doesn't allow controlling or changing the boost level.

The AEM unit is not a Piggyback unit. It controlls boost with the factory boost control solenoid.

Can you have a manual boost controller/switch in the car so you can change boost on the fly..?
