Default Utec - MBC question.

Simple question, I cannot find the answer... Is the MBC required to run with the UTEC?

It's not a MBC but a ABC. Read the UTEC user manual. The ABC is used to bleed pressure to the solenoid so you can reach the proper psi targets if your boost map does not get you there.

Reading this - http://www.turboxs.com/faq/wrx.htm - it doesn`t say ABC/MBC.. but I think I got the answer to my question.. Basically, without the 'boost controller' you may not reach target boost levels. Correct?

Ok, page 10 on the link above..

NOTE: You must install and adjust the ABC on your WRX for the UTEC boost control to work properly. If you do not intend to use the UTEC to control boost the ABC is not necessary Each staged kit runs boost levels higher than are achievable with the standard factory boost control system. The ABC must be used to increase the flow capacity of this system in order for the UTEC to control boost properly. The following are the recommended boost levels for each staged kit.
RPM/Stage Stage 1 Stage 2 Stage 3 Stage 4 Stage 4 FMIC
4000 16.1psi 16.5psi 17psi 17.5psi 18psi
5500 15psi 15psi 15.5psi 17.5psi 18psi
6000 12.5psi 12.5psi 12.5psi 16.5psi 17.5psi
7000 12 psi 12psi 12.5psi 16.5psi 17psi
So, like i said.. it is not required unless you want the UTEC to control boost.. But obviously to increase performance, it would be good to have.

lots of folks hit target boost WITHOUT the extra bleed.

others require it.

try it without, and take it from there.
