20hg is correct idle. 0 is correct if the car isnt under load, ie isnt moving.

If u mean FLOOR it and actually have the car in gear, then theres a problem somewhere. Check for blocked pipes.

hmm in my old beast sat negative pressure at idle
moving up to 0 during "normal" driving
up to 1bar of spirited driving with atmospheric oil spitting to go in toe

Yeah, I get about 11 - 12 psi in mine.

yep mate, sounds normal ish for an LCR - however looking at your avatar I'd assume you have an LC - 11psi sounds a bit high for an LC but its more than possible... think mine was about 9psi std, perhaps 10 now coming to think of it...

Get it remapped and that figure will almost double

 

[Empi5]

aye, peaking 24 psi under full load

Mine manages to pull -30 on overrun and sits at -25 at idle peaking up to 14 psi on throttle just a little concearned about the idle value
