That guage is very limited and will become [even more] useless if the boost exceeds what the guage thinks should be maximum boost. Ex, at current, the guage goes all the way to the right around 12psi, but then someone does something to the engine and increases boost to 17psi. The guage is now that much more inaccurate. Is it that hard to make a digital in-dash gauge? Boost gauges are for telling you if you're hitting the boost you're supposed to hit (down to a precision of at least 3), not for telling you if your turbo is working at low, medium, or high. C'mon.
there's 20 marks on the fuel gauge and the range is 0-20 psi so... if u haven't actually tried it, dont knock it. It works perfectly fine.

...so whats this low medium high crap you speak of? same works for the oil temp gauge
oil temp is a little different then reading boost where you'd like to know the precise numbers. If I should be running 12.3 - 12.6 stock and I'm running 10.1, I'd want to know, but unless I see the numbers, or have a more precise gauge, I wouldn't be okay with knowing that I was sitting a little over the 1/2 mark, but not quit half way between the 1/2 and the 3/4. Please don't make this harder to understand than it actually is.

If you actually need to know your boost to make sure you're not under/over boosting, this gauge is useless. If you just want to see that you're boosting "low" and then that your boost builds through "medium" and then "high", and you don't actually need the information... well then you should probably not even use a boost gauge because it's pointless.

i would agree with u if u were talking about AFR, but reading boost in whole numbers is not that detrimental. And I can accurately tell the exact boost pressure each time i drive because like I said, there's 20 marks on the gauge, so if i'm at 2 marks above 1/2 then im boosting 12psi, the same way any aftermarket boost gauge works...

Yeah seeing a needle pointing somewhere between a bunch of lines without meaningful numbers in relation to the boost is just as accurate as having a digital number that goes to a few decimal places...

Even if there are 20 marks on the gauge, they aren't numbered 1-20 and I'm certainly not going to sit there counting out the ticks from 1 to wherever the needle is pointing. And while you could do the simple math like you said, you still aren't getting the precision that you would get with a numerical read out. I'd still want to know if I was making 12.1 vs 12.9... maybe you wouldn't, but if I'm tuning the car and keeping an eye on that stuff so I don't blow my engine, those decimals make a huge difference to me.

If you think its useless then buy the P3 gauge which is a much better boost gauge and gives you a digital readout. I think any serious modder should have a dedicated boost gauge anyways.

I agree... but people want to keep the stock look and I don't blame them for that. That's why I think you should work on making a digital in-dash.

But I'm glad to hear you agree with me that it's a novelty thing for people who don't want to mod.

How many cars/tunes do you know tuning on the fly on a daily basis jpuff? A boost gauge is just there to monitor various spikes or problems that may occur on a car. It is a novelty, whether its digital or mechanical... the entire purpose is to see if there's anything major happening with the motor. What are you going to do on your way to work if you boost gauge shows you 12.9 instead of 12.1 target?

This gauge works just as well as any aftermarket gauge. Seeing the number "10"on a boost gauge versus "1/2" in your dash and saying that you can't comprehend the difference just shows that you have no idea what you're talking about.

Perhaps you missed my entire point about it needing to be precise. But allow me to elaborate for you since you didn't get it the first few times. i never said "seeing 1/2 doesn't make sense", I said that between the lines you don't get as accurate of a read, and if you're monitoring your boost to make sure you aren't over/under boosting, then you should probably have a more accurate read since every little 10th counts. And as far as people tuning on the fly? Everytime someone switches a "map", they're tuning. If my boost was spiking, or it was under, I would turn off the tune until I could figure out what was wrong. If you can't understand that or why it's more useful to get a numerical read, then I give up.
