My Ride: AA HKS Boosted M3
Boost gauge problem solved!!!!!!! I am an idiot!?! Lolz, wasn't the gauge. I had a small boost leak from the blower to the S pipe. I didn't see the leak because it was behind where I couldn't see! When I made adjustments to my S pipe, somehow it came loose off the back.

I just want to thank Jean at AA for being patient with me, he also referred me to some tech guys at AEM to troubleshoot. FYI, they had a great idea to check the gauge to see if it was registering boost. They had me hook up a bike pump with a pressure gauge to the sensor. I connected the bike hose and sensor with an extra wire. Turned the car on and started pumping! Gauge showed boost past 16 psi.... Duh!?!

Anyways... I'm putting out 9-10psi on the blower! Afr's look pretty good but now I think I'm ready to at least dyno....
