the mbc is on... but it's not letting me go to my desired boost levels.. you know how on internal WG's you can adjust the WG arm to raise and higher boost levels.. so i was wondering.. my car was boosting 8lbs already with the arm.. do you have to release the arm all the way down to a lower boost with the WG, then install the MBC or just leave the WG where it's at? does it matter at all?

 

If you want to LOWER boost fromstock you're going to have to modify the wastegate arm, otherwise you should be able to plug the controller in and go.
