just use a gm 3 bar map sensor found on the buick grand national. available at autozone and reads up to 3 bar of boost. and its a 3 wire 0-5v sensor. the pigtail connector is available also. or there is the map sensors offered by aem. nice stainless body with a pigtail included. it threads in instead of a hose connection. aem also provides the chart boost vs voltage output. Might be able to contact dyno-jet who makes chassis dyno's and see if they can help you with the software they use for boost and a pc for their dyno.
