Hey everyone. My boost gauge reads "0" with the engine off. Between 20 to 23 what ever at idle and a max of 5psi at full boost all the time. I have a Tial wastegate with the green spring which I think is 7.25psi or .5 Bar.
What gives?? Thanks!!!!

 

HAH Well First hook your wastegate line up the the IM instead of the compressor housing so it will run that .5 bar that you want it to. the 20-23 is inches of mercury and that is vaccum, that is good. 0 means there is no boost or no vaccum
