bullitt210,
I'm not sure, but I think most Honda PS systems have the boost determined by how fast you're going. So, I'd think there might be a valve in there somewhere that opens up to allow more boost at lower speeds...just a quess.
I'd take a peek at the manual for our 1996 Civic to see if that's similar, but I'm not where the manual is now...
As far as high pressure, I don't think the ps system is very high pressure.
