Do most of the people that have a MBC set the boost by trial and error, meaning set the boost and then take the car for a ride noting the max booost under OT and then stop and reset the MBC again. Is there any easier way? Do ya mark your 19psi, 21psi level on the MBC?

Thanks.

 

uhm, no i dunno how you would mark it, but mine turns in circles so... basically once its set, its set.. and i just turned it, stopped, turn, stop, turn stop, i did it on the highway
