Do I need a Boost Conroller with PowerFC

[derass]

I would get the Apexi boost control solenoid. Electronic boost control is the best method. Having the ECU do it is even better.

A standalone electronic boost controller (EBC) would be my second choice. Like a GReddy Profec B, or AEM TruBoost.

The HKS actuator would be my third choice. It's half the cost of the EBS options above, but gives you no ability to grow. IIRC, it's set to 12 psi. With your setup I'd be aiming for 15 psi (assuming you have >550cc injectors). But it's only a single boost pressure. The adjustable rod changes the boost curve, not the boost pressure.

My last choice would be a manual boost controller. They spike pretty badly and could end up blowing a motor.

This is extremely helpful, thank you.

The bummer is - as far as I can tell, the Apexi option is like $550. That seems like an insane price considering I got the whole PowerFC for not much more than that...but as you say, it seems like the best option. I just wish one would pop up used or something.

At the same time, it seems like the electronic boost controllers new and from a reputable brand cost almost as much anyway, so unless I got a good deal on one of those, it seems like I might as well spend the extra hundo and get the Apexi solenoid.

I have 550cc injectors for the build, so as you said, I'm figuring 15psi for the tune, so the HKS actuator is not an option for me.

unfortunately, if I have to cancel the appointment for the tune in 2 weeks, I won't be able to reschedule until the season is pretty much over...so I'm on a definite timeline here and can't wait around for a good deal to pop up.

If anyone finds a good deal on the Apexi unit (or is selling one), pls let me know, that would be amazing
