Correct procedure for adjusting Cosworth fuel pressure?
Hi
Can somebody tell me the correct procedure for adjusting the fule pressure on a YB please?
I obviously know that i need to adjust the fuel regulator but the info i am after is at what revs do i take the reading/s and do i do it with the vacum pipe on or off? Also what should the pressure be on a YB running stage 1 Dark blues and 15 psi on a T3??
Cheers Spadge...

Spadge,
Here's my preferred procedure: "pick up the phone and book an appointment with Mark Shead"
I have no idea, so here's a free
to make up for me being facetious (sp?)

All done 
Was reading nearer 4 bar at idle with the vacum pipe off but i'm guessing it was adjusted upwards for the stage 3 i just removed?
Is sitting bang on 3.5 bar now until i re-fit the vacum pipe and then it drops down to just over 3 is that about right Stu??

very wise stu...... would you think iwould get any gain or is there any point in fitting a fse power boost valve, instead of using the standard reg?
Been thinking about it for a while but not sure if its worth it really , whats your opinion?
Thanks mate!
