custom tuning in DFW
yeah my gauge is .1kg/cm3 off.....so yesterday when we had ur gauge on my car it was showing 23psi and mine was showing 1.71kg/cm3, but it should havbe showed 1.61kg/cm3. so ill tuen it down a little bit....
also my other question on why i called yesterday was....it spikes to 23psi in one gear and when i shift it doest go that high...it hits like 21.8psi...is that normal?
and regard to the MBC....i want the shortest amount of VAC line to the MBC and back to the VACsys, right??

the boost changing from gear to gear is most likely due to the boost controller design. the hallmans have a ceramic ball bearing which responds quicker then a steel ball. thus less boost spike because the ball has less inertia (the ball and spring ultimately regulates the boost) (it is also pretty consistant from gear to gear). even my greddy EBC has less boost in 1,2, and sometimes even 3rd gear then it does in 4th and 5th. i forgot what type of boost controller yours was, but if it is a bleeder type, then the spikes can be even more pronounced. and yes, you want the vacuum lines to and from the MBC to be as short as possible within reason. if you have a great place to mount it then i would mount it there, and run the vacuum lines as direct as possible.
