Autometer is the best IMO. But there are some really good brands. It depends which features you like better.
As for mounting, if you have the RPD, I don't think anyone makes a pillar with a gauge mount for the RPD, so your best bet would be on the steering column, I would imagine.

I've seen people attach it to the side of the RPD. There's a vender on here that has a piece that fits around the gauge cluster in your dash that has one or two gauge slots depending on what you want.
I wish they made pillar with gauge mount for the RPD. I've been looking for this for months... but alas...
Edit:
Found it. It was Cobalt Addiction. (https://www.cobaltss.net/forums/show...ht=gauge+bezel)
I also stumbled on this setup too.

Unfortunately the analog guage isn't a true analog guage though.. It is still receiving a signal from the ecm like the rpd does.. It's not physically reading vacume and boost like a real mechanical guage would.. Found that out when I got tuned and my guage was reading 19-20psi with the infiniboost.. Hooked up a true mechanical boost guage and it reads the correct 25psi..

it's fine you just need a mechanical boost gauge to read that high.. the RPD is based off of the stock map sensors and as everyone has said they don't plan on them going that high so it freaks out for a second ( the rpd) everythign is actually fine

You may have a code pending. When I first did the 25+ psi mod on my car, it would pull hard a couple times, then trigger a immature code and limit things. I disabled those codes and I get consistent high boost now. Im still running 25+ now, if I do a long 3rd or 4th gear pull and the RPD reads over 23psi for more then like 5-6 seconds, the data will blank out. Car still pulls hard, boosts right etc... Just no boost display on the RPD when it happens.
Not sure that this can really help you, this is just what I noticed when I did something similar to the infiniboost tune.

The car has a constant CEL, i believe it was p0106 and some other. p0106 kept coming back seconds after clearing it DURING a pull, BUT, it has been there before i ever tuned the car. This leads me to believe his map sensor is bunk.
Whats the best course of action... Just disable those codes? or buy a new MAP sensor?

Anybody have an explanation for it being that off? I wouldn't think it was scaling because then that wouldn't explain when you really do get 24-25psi on the RPD I wouldn't think...

I disabled all those DTCs just in case and also the DTCs for the boost solenoid because I have to unhook it to run my MBC.

The fact is that the number you are seing is the number the ecu is spitting out after it goes through all the conversions it does to finally end up with a psi number. So without a mechanical boost gauge all you are seeing is the end result of a mathmatical formula whether it be 1:1 or 0.8:1

Edit: Is this the same for the stock setup/tune? For instance, is 15psi always ~15psi when stock?
