T3 Cobra,
That should be about 15.5 psi. I have seen 15 on a really good day. 15 = 3:00 on mine. Is your needle on 0 when the engine is off? There is a small plastic stop screw that will "zero" the needle. It is actually an eccentric cam screw that doubles as the "zero stop pin". This adjustment could also be useful to "calibrate" the stock gauge to indicate the correct max boost. However, you would have to have an accurate gauge to temporarily hook up to see what your max boost really is. I was lucky enough to have access to a regulated air supply & an accurate secondary gauge to calibrate mine "on the bench". The good news was that I didn't have to do any adjustments. My gauge was right on.
How difficult was the modification to do? Are there any additional tips that you can pass along to the next guy wanting to do this mod? It's really cool to see the stock gauge bend around that far, isn't it??:beer:
