Boost Controller Setup

[QuickSilverGSX9]

This may be like reinventing the wheel, so bear with me. I believe, it is most common to install the boost controller (BC) on the wastegate and BOV lines. In other words, run a line from the wastage to one end of the BC and then a line from the BOV to the other end of the BC. However, I was thinking, if you pick a source for the boost controller, near or at the compressor housing, the turbo (generally speaking) would have to work less hard to make the target boost. If you have any leaks in the system and have the boost controller sourced from somewhere upstream, near the BOV or even the throttle body, you make the turbo work a lot harder than it needs to. So, I decided to install the BC between the wastegate and the nipple on the compressor housing of the T-25. I know it's not mindblowing, but I just thought most people run it from the BOV and not somewhere closer to the compressor housing. I would figure the benefits would include working the turbo less (sometimes) and possibly quicker spool and holding solid boost?

Don't know, just throwing it out there.

You're correct, the BOV line is the worst place to tap for your mbc for many reasons, what you have cited are just some of the minor ones.
