I read this under the search section:

"for the boost controller it should be routed to a non vac boost source..ie right after the compressor housing.. not on the uim or lim"

I have the Apex single turbo and the HKS evc ez boost cont. Can I tee into the same boost source for the valve controller, the one reads boost and the other t`s into the the wastgate. The problem is that the apex turbo and my piping does not have a boost source that is non vac before the uim,or the lim. Can I use the line that is on the back side of the throttle body?

The waste gate has never opened yet even with the boost turned to the lowest setting. I have pushed it to 1.2 Bar but dont want to go any higher.

Another quick ? should I set the My power FC at 1.2 bar so I dont hit fuel cut or higher?
