Boost levels at crusing speed

[june]

mine is the direct injected ZD30, before dawes and needle were fitted boost would do the same symptoms as yours. once fitted sits on 11 psi @ 100 clicks and stays there. don't know about common rail but fit dawes and needle as mudski suggested. [no more problems]

And block the EGR after the valves are fitted...

CRDs do get the engine code randomly (depending on temp conditions?), just clear it with an ultragauge/scangauge. Or drill a hole but that kinda defeats the purpose.

Zorst and EGR block will raise ya boost

Chip, Dawes and Needle will fix it all.

Yeah the Nissan service manager suggest EGR block & workshop foreman suggested Dawes valve! I asked what about warranty and the answer was it mite effect it!

Schanmala I'm running and Ultra gauge (great bit of gear) and the reason I found the issue. Will hopefully finish off wiring up the Autron gauges tomorrow & fingers crossed the Dawes valve turns up by Friday cause only 10 days and it's up the Cape for 5 1/2 weeks
