Hi Folks

Just bought a 2006 IV GU 3.0.

Bloke I bought it off didn't know what has been done to it, in fact was of the view that nothing had been done to it other than a larger intercooler and a catch-can. Obviously i don't know what I was looking at either!

Having had an opportunity to go over it in more detail, it's fitted with:
-a 3'' exhaust
-a Steinbauer power module
-boost gauge that's topping out at 9 PSI
-an EGT gauge which I only spotted on the drive home last night and which seemed to top out at around the 500° mark
-and this......which looks like a boost controller, but I've not been able to find an ARB branded version to confirm. The dial turms but there are no +/1 boost markings to give the game away.

Can anyone help by confirming what this is, and if it's not a boost controller, what does it do?

Any and all help is appreciated. Cheers
