hey im new to all this,
 i removed plastic engine cover, and i found the n75 valve is not present and the 2 pipes are joined together.
i also found which i think is wrong and have changed, that the actuator pipe was fitted in the air intake pipe ( kandn filter than the maf sensor i guess then there is a nipple in the pipe were my actuator goes to) i have removed this and fitted it so it is on the intake manifold after the throttle body.. i think what ive done is correct as now it shud be reading intake pressure not air in pressure.

so basically now there is no mbc and no n75 valve its just running actuator pressure ( im right arnt i) it now seems to come on boost alot earlier and is maxin at like 6-7 psi which i assume is what actuator is set at.

please help me get this goin right as its had all the money spent in the right places just been piped and messed with by a idiot i guess.

what boost wud be safe limit. if i have to use the mbc, also i cudnt find the electrical connector for the valve???

i also have a recipte for a n75j valve but it must have been removed by prev owner to fit the mbc wich now also is removed

Holy sh!t mate, get some pics of your setup and we'll try to guide you as to what the pipes should look like...

The way you've described means the ECU has NO way of controlling the boost even if it sees too much. One surge and you could have one of these
