That is exactly the set up I had. The MBC 'catches' the spike so it will not have a high spike but the N75 still controls the boost. I used some beefy metal Y pieces made to be used with carbs so they were nice and strong and they were also the same size as the tubing so there was no restrictions on flow. If your MBC has 3 ports then the one that goes to atmosphere could be teed into the N75 port that goes into the TIP.
