I fitted a boost gauge, mostly to re-assure me that all was working well, and not over boosting.
I too tend to back off the throttle once the boost starts to increase.
I have it in my mind, more boost = more power = more fuel = more money...:augie
When you fit a boost gauge, don't expect any boost when you are in neutral, even though you rev it to bits, it only comes in when you work the engine.
So take it for a run, steep hills really bring it in.
You will never get negative pressure, like on a Vacuum gauge on a petrol car, as there is no throttle to close down the air feed, unlike with a carburettor.
The boost gauge helped me to diagnose a recent faulty New exhaust fitted by Kwik Fit, it was when it was actually on boost that the horrible rattle started.
A different manufactured exhaust solved the problem.
So gauges can be useful... but only if you regularly look at them , and only then, if you know what the gauge is actually telling you.
On my boat, I fitted several gauges to the outboard, rev counter, hour meter, temperature, rudder position indicator, also I have two leisure batteries, I know exactly how much current is going into or out of each, and the voltage at the terminals. these are digital, but the rest are analogue.
