I was wondering what kind of max boost pressures the stock sensor will show when a monitor is plugged into it. IE what's the max pressure the stock manifold pressure sensor will detect before over ranging. I am currently running old Issopro gauges 0-35# boost and pyro. Boost guage pretty much maxes out on the 100hp setting of the quad race box and I was looking to upgrade everything (Quad X2 race and new gauges or monitor)

 

right around 40psi i think

 

I think that the stock ECM limit is 44 psi. Mine throws an over boost code when I go over that.
