Scenario: (91 t-leg) Finally finished installed my apexi s-afc, and greddy e-01 boost controller last night (left over from my wrx). I am de-snorked, awaiting my 06 intercooler, so I was just trying to go to 10psi. Start dialing everything in, adjust my idle, make sure I'm safe with the s-afc. Go out for a test drive, boost will spike around 9.5psi and then just drop off to wastegate pressure, meanwhile the greddy bcs is reading 100% duty cycle, with no change in boost. I think the car may have been doing this before the attempted adding of boost, however I just don't think it was as noticeable with lower boost levels. I'm going to put a vacuum pump on the wastegate to see if it holds any vacuum, I think I may have a problem with the diaphram. Anyone else have any similar experiences?

Also I was wondering if anyone else has been running/has run the apexi s-afc on thier t-leg, I would like to talk to you about your results!

Thanks for reading!

Update, left a vacuum pump on the wastegate actuator yesterday, it's holding fine... I'm suspecting the boost controller itself is at fault now since I've been through everything else. Going to swap in a manual bc and see if she'll hold it.

Just got off the phone with greddy.... They are trying to convince me the vf11 is too small/responsive to control boost properly... I don't know whether or not to call bs on this.

Why did you switch to the greddy boost control solenoid? The stock solenoid does essentially the same thing.

Does Greddy unit have its own controller?

Yes the greddy unit has its own control unit, lcd screen, solenoid, and remote. It used to be greddy's whoop-ass controller that interfaced with the emanage when it was still being made (the e-01 that is). I have already installed a hallman mbc, and am just going to get rid of the e-01. For anyone curious, link to the e-01 on greddys site:
