Changeover pressure monitor
Has anyone ever done this?
T off your changeover flap actuator vacuum hose and monitor the movement with a pressure gauge ? I did this yesterday and its def not what I was expecting.....Im thinking my pressure converter is crapping out on me but Im not sure what I should be seeing.... Mine is staying at 25psi utnil I shift, then its dropping down...I would have expected it to slowly drop down as I gain in rpm/load. |
