as for units, me too. As far as I know you have normally -19 - -21 what? PSI? I found a pressure converter somewhere and the only value that fits was foot of something. Please let us tell the correct units, there are several people around the globe in this thread involved.
Just for clarification:
I'd -0.62 bar with stock cams AND WITH Tomei 256 cams.
Now with the 258 cams I have barely -0.54bar at idle. I might have an explanation for that behaviour. Maybe Tomei improved the cams for VVT, i.e when the engine runs VVT in 'sharp' mode. That would explain the massive power drop below 5000.
And if this is the case, I'll kick out the 258 right now. I actually bought them to improve lower and midrange, i don't drive the car in every gear to redline.

So, -0.52 bar literally falls right where I am at with mine . .
-0.52 BAR = -15.35 In. Hg
My car reads at around -14 In. Hg after the 258 swap
Your stock cam and 256's read at -0.62 BAR (-18.3 In. Hg)
-18 to -21 In Hg is the normal for SR20DETs with stock cam shafts at sea level.
So, your drop was about 3 In. Hg and mine was more like 6 In. Hg, so a little worse.
Still think something is wrong with my setup even though the car runs great and everything. Its just driving me mad! :-(
