Default How accurate is the factory boost gauge compared to other gauges?

OK - BESIDES having to convert from mpa to psi, how accurate is the factory gauge? My top stock boost levels according to the gauge are right around .09 - maybe a little higher, so 13 psi if you convert it. Isn't stock supposed to be at least 13.5? I am wondering if the gauge is accurate.
Anybody compare the stocker w/ other gauges?

My stock gauge is off a little bit as compared with readings I get from my AP. I'm not sure which one is more accurate. I would assume the AP is since it's going off of information from the ECU, but that's just a guess.

Was the factor one running higher or lower than the AP readings?
I have an AP on the way.

Me too...and it got worse the longer i had the gauge. The "zero" point got lower and lower.

Omori > OEM.

Pop the gauge out and put a 45mm omori in the pod.

yep.
you can clip the wires and soldier,
plug in the hose and you're good to go.
Hardest part is getting that 45mm guage
into a 42mm housing. I think J-spec tuning's
web page has directions on the install....

My factory gauge is pretty accurate. This was the case with a Blitz SBC-iD, Blitz BLM boost gauge, and now my Greddy boost gauge. Also matches up with what I'm seeing on DD. There are some that aren't accurate though. You can tell when the engine is off, the needle won't point directly in the middle of the 0 hash mark.

Installing the Omori into the Lamco pod looks like a real PITA.

i have been VERY happy with my autometer electrical boost gauge.

auto zeroes every time you start the car... readings match the utec logs very closely,and i use the peak recall function WAY more than i thought i would.

Within the error of reading the small boost gauge, it seems as accurate as logs from my UTEC.

Also would like to find a gauge that reads psi to fit the factory steering column boot.

When I tested my OEM gauge:
.05 = 7.03psi(should be 7.25)
.07 = 9.87psi(10.15)
.08 = 11.28psi(11.60)
.09 = 12.82psi(13.05)
.10 = 14.35psi(14.50)

I thought that .10 was supposed to be 14 psi ?

And by the way, the only 45 mm gauge I've been able to find is the Omori. This would be a lot simpler if there was a 42 mm aftermarket gauge.
J-Spec Tuning does have the instructions on how to put the Omori in the factory column-mounted pod on the website. CirrusWRX is the one who first posted them. They might be on scoobymods also.

Like I said though, it looks like a real PITA.

Yup. Thank you - I found a conversion calculator.

http://www.onlineconversion.com/pressure.htm

For everybody's reference, here are the calculations:

.1 mpa = 14.5 psi
.09 mpa = 13.05 psi
.08 mpa = 11.6 psi
.07 mpa = 10.15 psi
.06 mpa = 8.7 psi
.05 mpa = 7.25 psi
.04 mpa = 5.8 psi
.03 mpa = 4.35 psi
.02 mpa = 2.9 psi
.01 mpa = 1.45 psi

Thanks one on order. Doesn't look that bad - that a little water base silicone lube wouldn't take care of.
