I got a Apex'i PFC if I was to get a profec B boost controller and crank it up to say...13psi, would I still get boost cut or is there something else I need?

What I meant to say is.



With those combined... would I still get boost cut at 12psi or would it just keep going up with no boost cut.

the PFC controls boost and you can adjust the boost cut via the commander. its pretty nifty

well I've noticed that I haven't really hit the boost cut since I've had the PFC and ran it at about 11.9 psi but whenever I get it to boost it doesn't always hit that point. I found one that is really cheap and was wondering also if it is sharper than the PFC at boost control.



Cause I don't like running once and seeing that I was only hitting 11 psi during the race instead of what it is supposed to hit.



Plus I wanted to crank it up to 13psi.

The PFC will control boost to whatever you set it at. It wolnt ever cut fuel UNLESS you overboost your target by .25 bar.



Now, not having enough fuel could become a factor...

I was always told the the PFC dosn't do a good job of controlling boost. If you want to control boost accuratly with the PFC then theres a little boost control solenoid that plugs into the PFC. Its on the apex-i website.
