MBC not working well, what could be wrong??
I just put in a Hallman boost controller in my car and after the install I proceeded to raise the boost. I turned it all the way as far as it would go and my boost isn't exceeding 15psi. I am sure it is installed right and even tried another one of the same brand and I can't get anymore than 15psi. from this MBC. What could be wrong? I figure I should be able to get more then a 1.5psi increase. I was hoping for about 16 to 16.5. What should I do

I, have the Hallman Pro installed, set at 16psi. I haven't tried any more but it definetly hits 16. I'll turn it up a notch and let you know. Did you unplug the stock solenoid or just plug the hose? I heard if you don't unplug it it will burn-out. Mine is just plugged per the instructions. If it was unplugged would it effect the ECU? Know anything about this?

yup! just installed mine, if you didnt buy the one that comes with a heavier spring then you cant get anymore than 15 lbs. so try the heavier spring, its super easy to change.
