never went into vac. but the boost would surge up and down between 0 and 10 psi.

not to offend anyone, but its really not that tough to follow the directions, pull vac lines and install them on the mbc. Should take all of 10mins to setup the mbc, install, and tune the mbc.

you didnt offend me but its not the directions that get me, its the mbc working for 5 mins then peaking and immediately dropping into vac

have you checked to see if the brass fitting holding the b&s is tight? Still think your not setting the b&s tight enough.

you were right earlier when you said that I had to go somwhere and didnt get time to tune it comepletely so I just had to plug my N75 back in and I am just going to calibrate and start over tomorrow

I feel your pain zero... mine just messed up again UGHHH... [sm=sigh.gif]
