Default SAFC and Boost gauge read different boost levels

My safc reads boost at .18bar and my omori gauge reads .3 bar. This is an HKS kit that says the stock boost should be at .3-.4 bar. Butt dyno is unsure of power gain, real dyno on tuesday.

What do you suppose is more accurate? The omori is tapped in to an EGR vacuum line with no other sources tapped into it.

the safc is electronic therefore will have a more accurate reading. many brands, including autometer are notorious for inaccurate boost readings. go by the safc

i have afc hack and the afc reads about .05 greater difference from my blitz DTT and my autometer boost gauge...the blitz and autometer are exactly the same as one another...

I'm pretty sure that 760mmHG(millimeters of mercury), is equal to 1 bar which is equal to 14.7 psi. I'm not 100% positive, so maybe somebody else can back me up for sure.

762mmHG = 14.73PSI, that is correct sir!

I think I am going to go by the omori. It responds better to adjustments made with my boost controller.

Mhmmm my VAFC and autometer gauge were off too, switched to a greddy gauge and now they read just fine.........

Just in case.......is the sensor type set to 6 in 6 out? Just wondering.......

Anyway, it is just 1 psi off, and most gauges are not that accurate when measuring really low pressure, especially if the scale is very large.

it is a 1.0 bar omori gauge. Yeah, my SAFC settings are fine.
