Yea, this weekend I'll take some time to simplify the fuel stuff and get rid of a bunch of intersecting lines. Re plumb the vacuum things and run everything off the back end. I hope this solves the oscillation.
I'll relocate the sensor to the frame or firewall, but it says in it's specs that it's able to withstand vibration from 100-20,000Hz, 20g sinusoidal.

FWIW I was on a MAC valve, we couldn't get the one that came with the EFR to work at all IIRC.
I'm following along closely here. I'm going to tap 18psi when it comes time to get the 4 port valve/2 port actuator working, hopefully with something other than the 1.3.x or 1.4.x I'm running now.

So... The plenum was siliconed gross. Probably when the shop sent the injectors out for cleaning. Stuffed the runners and cleaned the surfaces and laid out a new gasket. Thank God I have so many spares.
Mounted the MAP sensor to the firewall and tee's off the back port per Mt.Net SOP.
The busted *** fpr hose was too tight of a fit to use the same reference so I ran a skinnywinny hose to the top mini port of the intake manifold behind the throttle body
So far, log looks a lot better and seems to have cured the oscillation. From a 4th-5th-6th pull, things looked great but there was a surprising rpm blip which freaked me out so I shut down. In the forthcoming log, it'll be apparent in the end.
Thanks Miataturbo!
Will post up soon, but for now some hipster ****:

its hard to diagnose boost leak with a powerful/capable turbo and speed density, because often those two things will just mask the leak. on mass airflow cars, a leak like that would cause the car to flip out entirely
that, sir, is called overboost protection/boost cut
as I explained in the email, looks like the car's making more boost now that you fixed a leak

Raised the boost cut and now it's pretty cozy. Feels great.
I've been sick the past two days. In that time, I got my car inspected yesterday, had to fix my horn on the spot which I totally forgot about. I'm not sure why I didn't take the 10 minutes to do this before. Among other 'interestingly missing' equipment, I passed.
Picked up 12 gallons of e85 to help flush and change over whenever that time comes.
Today I'm off to Seattle for the Labor Day weekend before I head out again for 2-3 weeks later in September.
Future projects:
Oil cooler hoses (why did I wait so long?)
Revisit oil drain scheme (Thanks Aidan)
Flanges for brake ducts
Weld on that 4th hanger Shuiend gave me a year ago
New catch can setup (Vibrant 2 port happy face can)
Fix A/C (will need new condenser)
Radiator ducting
Splitter (kmo25 ?)
MAC EBC/2 port Wastegate?
