There are many ways to run the MBC, i'd recommend some reading in the 1.8t section on Vortex.

My setup is great for me, boost comes on strong and fast, but after the initial surge is regulated by the N75 as per stock.

Doing it this way I am not controlling peak boost. The problem with running a BMC only is the throttle response can become very jerky, if I wind my MBC too high, the car is uncomfortable for normal driving.

Lots of options, cheap to test, just go slow as you will change parameters the ECU is not initially expecting.

A MBC won't be much help with holding the boost into higher revs, that is an issue with the turbo's flow. My boost is probably at 90% by 3k rpm, so I don't feel the need to redline it, if anything the Bmc in this configuration probably makes the boost roll off earlier.

On the up side, the torque at 3k has never been stronger.
