In my scangauge setting I can switch it from reading MAP or PSI (boost). Does the Fiesta not transmit the data in the same way? Or I might be talking out my a$$ since I've never driven a forced induction car...
Harbor freight has cheap boost/vac gauges which is a good instrument for eco-driving in general and would be worth the money and time spent...
