My Audi A4 is the very first car I've had with a turbocharger. I've known about boost gauges for a while, but have started thinking about what said gauges actually do. Most of the websites I've read say something along the lines that:
- A Boost Gauge is a necessary tool for keeping tabs on how well your engine is functioning
- A Boost Gauge will give you a better feel for fuel consumption
- Boost should never exceed 101.3 kPa/1 Bar/15 PSI/760 Torr/any.other.nonstandard.pressure.unit.equalling.atmospheric.pressure
Should I get one? If so, is there a good (i.e. useful and not exorbitantly expensive) gauge to get?
Just kinda curious.
