I have a new aem tru boost which reads up to 29psi for 260$ firm.
The AEM TRU-BOOST looks like a boost gauge and works like a boost controller. It's easy to set up and use right out of the box. Two buttons on the face help navigate through menus.
I also have this optoinal sensor for 120$ firm as they are 150$ new.
AEM offers a 75 psia boost sensor for high boost applications (sold separately).
Pm if intrested no lowballers.
