for those who have setup closed loop boost control with EFR IWG, what's your experience been like?

I'm putting in a 9180 IWG in my FD with Haltech Elite 2500. Just doing my homework now to see what's the best way to control the boost.
target boost 20-23psi (road race car)
using turbosmart singel port actuator (14psi), and EFR stock boost control solenoid.

 

Sorry to see you didn't get any replies. Did you have any luck pursuing this yourself and if so how were your results?

 

Seems to work just fine for me, I don't see why it would be a detriment unless it's setup way incorrectly. Get your base duty numbers about where they should be to get you to the boost level that you want to be at, then use the closed loop feedback to have your ECU do some light adjustment. Start with low P and I numbers, raise them until your system is responsive enough but doesn't wander back and forth. It can be a little intimidating at first, but it's not too terribly difficult to do if you take your time.
