HI MH have you tried stretching the dawes spring a tad, bare in mind its hard to "UN" stretch,
not impossible though. You can get heavier springs from somewhere to suit the dawes

Havnt tryed stretching the spring yet... Thought it would be ok as its brand new...
Not always thats why someone, Darren Dawes I think supplies
a heavier spring to allow more boost to be screwed in

Here's couple pics of how iv got it setup... Maybe some one can correct me if I've done it wrong or missed something...

3 ports on solenoid blocked... Line coming off airbox to front of needle valve...

This pic shows t piece.. One hose coming frm needle valve... The other coming frm vac pump wiv green inline filter and the third going to Dawes valve..

The black hose going streight onto the Dawes valve is the black hose coming off the t frm the needle valve... The 2nd hose at the 90 degree angle is going back to the actuator... And the rear port if the Dawes valve is going to a t piece.. One side goes to intercooler pipe showed in pic below and the other to the boost gauge...

Have I missed anything... Havnt tyres stretching the spring just yet but might give it a go...
If I adjust my needle valve will it adjust my power delivery curve? Will get close to full boost (15-18psi) just over 2000rpm... But after that it's like nothing happens ... By the time I get to just over 3000rpm I'm seeing a solid 20 pound on the gauge... I'm wanting to make the power curve bigger say frm 1k to 3k then for it to drop off after that... At the moment it's going frm arnd 1000rpm to just over 2000rpm.. Theres the slowest pickup between 2-4k in rpms...
Everything is hooked up right. Adjusting the needle valve will affect the boost curve, I would close off the needle valve more and try that. It seems that the needle valve is still open a tad too much maybe. Don't stretch the spring. Your Dawes has the stronger spring in it already.Originally Posted by mullet_hunter
I have been/ was trialing a 1mm larger ID hose to the boost side of the Dawes and I saw slightly better results. PM me you details mate and I'll send you a metre of it to try. If you want to try a new spring I also sell them too, but i don't think this is your issue.

Cheers mudski... Will have a play around with the needle valve and see what happens.. It's currently more closed than open... Not to sure what's going on with the Dawes valve.. All looks good but I've got it wound right in til there's no more thread... It drives ok but it feels like as soon as it reaches 15psi it maxes out.. Like u can put your foot right to the floor and nothing happens? Feels like it's not only restricting boost but overall power... Thanks for the offer with the larger Id hose... If I can't get it set up how I want it.. Il be getn a diesel smart actuator set to 24psi... Herd they go alright... Also looks at one of there smart xt modules.... At e moment my egts are really low... And the 250 mark...
open the dawes valve up to about a good 1/4'' or a tad more and work back from there just a bee,s d ck at a time will take a while unless you snag it first up
Yo MH what type of vacuum hose are you using, its not collapsing on you.
just throwing stuff out there, seems EFI fuel line works a treat, only 25c a mtr
Some of the fancy silicon stuff is shite
