i just installed a hallman mbc and have no controll over boost. the car is trying to go way over 20psi at 1/3 throtlle. any help would be greatly apreicated. turning the controller seems to have no efect on boost lvls

 

try a search for 'mbc install'
sounds like to need to remove the knob and adjust some part.(like some screw) not sure what cause i never heard of this problem

 

in cockpit adjusted? I know you have to adjust it different at first, someone else had that problem. do a search on hallman controller, it was just discussed recently.

 

keep us posted!

 

I would say just double check your lines and make sure everything is hooked up to the correct place...perhaps you tapped the wrong line or left somthing uncapped?

 

Turn the knob all the way out, not in.

 

Yes!! Make sure you turn the knob counter-clockwise (lefty loosy, righty tighty) all the way out and then make your adjustments.

 

so what happened?
