how long have you been running the EVC?

my EVC 5 is pulling reference from the intake manifold, pressure from the hotpipe about 2in from the turbo.

Boost guage is t'd into the FPR vac line.

When i was having boost control problems with mine here's what i tried. Turn off the EVC, make sure the actuator is doing it's job first. with the EVC off you should get a solid boost reading. if you have problems still then start checking for couplers busted (may be torn but only leaking at Xpsi boost) check all your connections are snug (i've blown the vac line for my map sensor off the manifold, scared the crap outta me) if no problems then check all your evc connections and settings. (mine has a switch for swing type and poppet type wastegates don't work right unless he correct ones set) then recheck for leaks.

P.S. where are you tuning it at? I see your in NC, so am I
