I know Nistune has a Boost Control feature, so why not a closed loop BC ?
Even without a factory pressure sensor, maybe use a device like the DLP with an aftermarket pressure sensor ?

Closed loop Boost Controller
Some S14 have a factory boost pressure sensor wich send to the ECU.

Re: Closed loop Boost Controller
From what I know the boost sensors were used for overboost cuts in some earlier models. Not used in later models
The Nissan ECU just has tables which adjust boost based on current gear/speed ratio and also throttle position. I guess also factoring current boost feedback was not a consideratino as the table was just a duty cycle control for the factory solenoid setup
I would say it may be possible to implement some closed loop system and would be interested in looking into that as a future subproject once all the other items on my list are completed!
