Looking to fit a boost gauge in my m240, got a rough idea having done an Audi few years back, anyone done it before, where to tap off boost pipe, not looking at the wired in digital just a normal piped pressure gauge.

Just thinking that the computer must know what the boost is. Would be great if that info could be fed to the existing MPG gauge. An MPG gauge makes no sense in a performance car with built in trip info. Any wizards here know how?

Heyyyy I mean the MPG gauge is handy when your miles are being paid for work, slap it in eco for a bit haha.

But yeah I know there is vent replacement digital boost gauges surely there is an analogue one or a way to map the digital signal to one.

+ one on the vent gauge. I scored one used here on the forum for half price. Five minutes and you have all the info you could ever want. No tees, or lines to run.

Used performance gear usually goes for ~50% of retail, so you're right there.

It can vary, of course, but my experience is ~60% for new or very lightly-used gear down to ~40% for well-used gear showing signs of wear but still in very serviceable condition. Paying more than ~60% for newer parts doesn't make any more sense than paying less than ~40% for worn-out parts.
