Guys I’ve been lurking for a while and have searched but have come up empty therefore I decided to ask for help. I just installed the aem tru boost controller I was attempting to set everything up and I believe to have altered the boost duty cycle. My car is 100% stock. At the point I installed the boost gauge and controller as a precautionary device. Can someone tell me what the duty cycle is suppose to be set from the factory so that I can confirm the setting?

Thanks for your your help in advance!

 

I just hit AEM TRU BOOST SET UP By Google search and it spit out a ton of Youtube videos.
maybe one could possibly help you...Good luck.
