I think I am goin to buy this MBC but the only thing I dont like is there is no locking nut or other device... has anyone had any problems with the knob turning up or down inside the engine bay... I just want to ask you guys before I purchase... I have my boost guage coming and I received my emanage today... this is the last on my list for this install...
