Boost Controller

[marktara]

Is there any to use a ohnm meter or some thing like that to see if my booster controller is working. When I unhook it I still get 12 psi, manufacture says little screw will keep turning until you find the "sweetspot", just thought there must be a easier way than turning half a turn the going for a drive.

I put a potientiometer in the dash on my 94. set it to 10ohms and get 4lbs boost at freeway cruze and 10lbs max under full throttle.

You should be able to check it.
Remove it and put the meter leads on the center pin at each end on it. Then check from the center pin on the end that plugs into the truck wiring and to the pin that the black wire goes to.
There are several ways that it could be made so this is a place to start.

I used to adjust it the same way Whatnot did. Always took it off the truck, connected meter and turned screw.

I think it's much more accurate that way than 'A Quarter Turn'.
