Prosport Gauges?

[Sharingan 19]

+1 for Prosport. I broke the little clip that plugs into the gauge installing mine a couple years ago, went down to the office and they gave me a new one.

Only issue i've had is that the boost gauge seems to read 1-1.5 psi low,and rarely sits at 0, but I mounted the sender in the engine bay in the pass side cornor so perhaps I need to relocate it or get another sender....or both.

Do you live at a high elevation above sea level (i.e., Denver/mountains)? If so, that may explain the 1~1.5 psi lower readings. Your gauge is reading absolute pressure, so as you go up in elevation air is less dense and ambient pressure goes down. If your gauges were calibrated at sea level (i.e., reads 0 when engine isn't running & gauge is powered up), you can expect them to read less than 0 (a little vacuum) when you at a higher elevation, and all boost #'s would be lower as well.
