Hi Jaemus,
Your manual boost controller valve is an industrial instrumentation type valve, possibly a needle valve, which should give quite precise adjustment.
As you say it's not an automotive valve, but I don't really think that setting would alter easily.

 
Ahh, that makes sense, I did find it seemed very precise when I was blowing through it and adjusting the valve. Which is a super scientific test! Thanks for the info :)

Is it just me or do the plates look a little larger than normal? Like a 120% sized plate.
Either way 20OOT makes sense to me...

 
The plate is same as JDM size (you can see how it fits in the smaller JDM rear bumper cutout) but the numbers are much smaller, to match our local ones. Something about wanting to make sure there is nothing to stop the government continuing to strip cash out of us on the roads...

Number plates look like SOOOT to me, thought you might have done a Diesel conversion 

Time to roll some coal?
