manual boost control in cab

[joel w]

hey guys and gals, anyone running incab manual boost control? i am curently using a stock actuator and a cheap boost/bleeder valve to raise boost but it overshoots sometimes and works best under the hood close to turbo.

but my friend uses a modified air regulator with a dual port waistgate actuator diapham to more acurately raise boost on his turbo rig with less overshoot and faster spool up. So i welded in a second port on a spare actuator i had laying around and sealed all the leaks on the new side of the diaphram. It seems to work properly on the bench and i am installing it tomarrow. ill let ya know if it works with the idea being that you put pressure on both sides of the diaphram to keep it closed harder and close faster...? just wondering if i am alone here or any one else is running similar boost controller.

thanks ppl..
