I see...then it may be that you have a damaged JB4 board. Replacement boards can be purchased here...

So I soldered the 4th diode back on and now everything seems to be working.

Will confirm with some 100% pulls as soon as these floods settle down under

That's odd...that would mean you are no longer running ISO.

I don't know what to tell you.
I did a 3rd gear pull in Map 2 and it seems to be maintaining boost just fine.
Logs attached.

Log appears to be good... that being said, when weather clears up please get another log with traction completely off.
