Hi all,
I searched and think I did it right but I am getting a few problems that I expect are related.
First, I went to AAM to have my car tuned. I have the 88mm pulley on a GTM stage 1.5. Since I couldn't get the canned tune from Gamma I went up there without testing the setup. Mike tuned it but surprisingly it was only making 7.5-8 psi. From reading this pulley should be making 10-11psi. I wasn't sure what pulley I had at the time so I went home "happy" with my 420whp thinking I would get a smaller pulley and go back. Got home and measured the pulley on the inside ribs and got 88mm. The sadness set in.
Poking around for leaks I noticed that my BOV was venting/leaking at idle. So I figured this probably explained the lack of boost. Thinking if it doesn't function right at idle no way it is doing what it should under boost.
Not wanting to make any changes without having a boost gauge I could easily monitor I set about installing my gauge. I tee'd off the line running to the BOV think a) if it was good enough for the BOV it was good enough for the gauge b) if there was a problem with the BOV not getting the right pressure to actuate it that I would be best able to diagnose
Having done that I went for a test drive. Vacuum seems good but I am seeing less than .1 bar / 1psi at red line. So I cranked down the BOV as hard as it would go. Got a bit more boost right around .1bar / 1-2 psi.
So before I rip my front bumper off and start searching for leaks I wanted to ask if this was the right spot to hook up the BOV and gauge. I also welcome any other thoughts.
Other factors.
I have HFCs. I think the GTM kit works fine with them from reading
The car was originally throwing a p006a code but Mike tuned it out.
