Hi, bros, Today I've tried to connect my mbc in such a way that it would act as a overboost helper, but it seems it doesn't work as expected. Could someone help me with this?  Looks simple right? I've bought two T connectors and connected everything except for mbc now. In picture it is shown as a two ports controller, but my mbc came also with one way T connector  Need help on how to connect this. And thanks guys  |

1) What do you mean by "overboost helper"?
2) I don't understand what the supplied one way T is for.

i have used that type from ebay before and it doesn't work how it should... believe it or not the ones made from brass plumbing fittings work much better!

say that the wastegate spring on a new turbo is stiffer and the n75 way over shoots you can use this crude method to stop crazy spikes |

Have you tried connecting mbc in parallel to n75 as in diagram? |

Just tune your PID correctly, and you wont need an MBC  it's a huge hack anyway. |

I know  Im trying to do this as a safeguard while adjusting KFLDR ) even small K03 at hardcoded 80% wastegate can reach > 1.5BAR of boost and ecu starts to cut throttle like crazy and I can not properly log anything to properly adjust KFLDR |

Forget it. Just having an MBC in your plumbing alters the behavior of the system. If you remove it you'll have to retune all over again.
Just tune properly. Start low and work your way up.
I'm telling you, ditch the MBC, it is a waste of time.
