Help installing manual boost coontroller

yep that's right. you need to block the hole on intake because it will pull in unmetered air on the wrong side of afm so will mess with your afr's
and as said I take it you are running a gauge to monitor over factory boost settings

Thank you so much for your replies. Yes, I do have a greedy boost guage which i plumb dedicate from the quad throttle.. I just made a test run and it turns back to .5 boost so I'll try to adjust on it.
