Turbo Boost sending unit

[Clockmike]

I have a 1985 911 Carrera which has an aftermarket Protomotive stage 1 non-intercooler turbo kit installed. The former car owner installed a tachometer from what I believe was a 930. This tachometer has a 1 bar boost gauge on it. This turbo kit runs .5 bar boost. My problem is I do not have the proper sending unt according to North Hollywood speedometer. the gauge does not move at all under operation. My sending unit is a 993 0-1.5. and I need one calibrated for just the one bar gauge.

Does anyone know what the part number would be for a sending unit calibrated for a 1 bar gauge? Specs are not listed on parts listings. Even the dealership needs a part number and does not know what the senders are calibrated for. Thank you.

pretty sure all Turbos use sending unit 993 606 103 01

I don't think so after speaking to North Hollywood Speedometer. They ohm tested both my gauge and the sending unit.
