best way to hook up MBC

I have a forge MBC
I have searched but no one has confirmed that one way is better than the other.

Would like to find out from guys have tried the one way or the other

1: MBC to Wastegate and turbo housing
2: MBC to T by the BOV and to Wastegate.

Another thing, by the BCS there is a pipe leading to turbo inlet, can I leave it on and just blank of the one side of the BCS.

What are the pro's and con's of running them in the different configarations!

I have read that with the 1st method there is still a bit of taper, where as with installation no2 you do not experience as much boost taper and a smoother boost curve

Granted there will always be taper because it is only a 16g at the end of the day it falls flat at 6k rpm
but we want to eliminate as much taper as possible

your views would be greatly appreciated

Thanks

Forge recommends installing to wastegate and turbo housing. This question comes up 3-4 times a month. I'm surprised you couldnt find any info on it.

I chose option 2, but maybe you should experiment and find out what works best for you.

Keep the reference line after the intercooler and throttle blade. So that means a port on the intake manifold.

Correct..... just letting you know where it should come from. Not just where to -t- from.

I would like to know this as well, this seems like it would be easier then to have to mess with removing it and pluging both ends?
thanks,

I ran my MBC from the turbo outlet to the wastegate. Now that I'm running Forced Performance's outlet pipe on the EvoGreen, I have my EBC hooked up into the BOV line.

If you're still using the stock outlet pipe, use that as a boost source.
