blowing off my boost??

so first off does anyone have the diagram for the 3 prong boost controller using the N75 valve??? but i got really bored with the 14 psi i was getting with the k04 flash. so i put the MBC on i had laying around in....yeah its sweet spikes at 22 psi holds at like 20 psi( only in 4th gear..which is also weird) but also if im not getting on it(more then 1/4 throttle) the turbo will boost at im geussing the 20 psi but its blowing off and dropping to 10 psi until i get on it some more ( i have the race N75 still connected but not doing anything) is this the problem with using only the MBC.. am i going to blow something up!?

read post 23 and 24........... i have no clue as to the boost build up......... i know with my car since i have done the stuff i have lately...... and running the forge 004

if i give it more than half throttle..... it blows off alot........ so i just go half throttle....... and let the boost die off

so at less then 1/4 throttle you build boost and then it drops off and then builds up and drops off? what kind of dv do you have and what kind of spring is in it

Turbo, I was wondering if you also have a diagram for the Forge 004? Thanks =]

what kind of diagram do you want? its a bov not a mbc

I bet your running the stock dv...  You cant use the stock dv with 22psi.. You shouldnt even use it with 14psi.
 

hes got an r1, and his boost controller is a 3 way.

yeah i need the 3 pronged MBC the forged one...and im using the APR R1 DV
if i go at anymore then 1/4 everythings fine but like just driving around it will go to boost more then 10psi then just drop off the 10psi while blowing off the rest of the boost  

btw..thanx for doubting me so quickly b5 owns

sorry, didnt mean to do that, just that alot of people just throw on an mbc and dont do any research
