Apexi Power FC Boost Control - Apexi Kit or MBC?

suby25 · 09-07-2008, 10:38 AM

I'm getting mapped at the end of the month and am debating on boost control to use with my EJ20G swap. I will be using the PFC as engine management and have ordered the Power FC specific boost control kit from Apexi, as well as a TXS standard manual boost controller. I have heard mixed things about it's performance. I like the fact that you can set the PFC to fuel cut with the Apexi kit, but with a MBC this is not possible. Can anyone offer input on how well the Apexi kit functions and regulates boost?

Use a combination of the MBC for primary boost control and the PFC as a failsafe in case your MBC breaks the spring or something. Protects against boost creep, too, like a backstop.

So you can set the PFC to fuel cut at a certain boost level?

Interested to hear more reviews of the Apexi boost control kit... seems to be relatively uncommon.
