Just got the ERST back on the road and its running like a dog with a slight misfire but while its on tickover the boost gauge reads -8 is this right, this is my first turbo so I'm a bit green on that sort of thing

 

mine reads bout -15 to -20 i think



u may have air leak i reckon

 

that will by inches of mercury, which is half the size of PSI, so 8psi = 16 inches of mercury - which is bang on

 

Yeaaaaaaaaaa whatever that means
