To much boost

[Rex13]

Dont worry im more confused than you mate.

Yer first it was getting to much boost, now that i wound in the dawes valve fully im getting 13psi with no limp mode and high egt at about 500 degrees

I cleaned the dawes valve yesterday but all seemed good.

Yeah more than likely. Low boost and too much fuel will make the egts be higher than normal. I'm gonna say your intercooler is leaking, thats why you can't reach boost. when your winding in the dawes to increase your boost, all its doing it pushing that extra boost out of where ever its leaking. But. Open the Dawes up and see if the spring inside hasn't bound up and the ball it seating right while your there.
Edit :
I'm a little confused now, first your boost was too high, now you cant get it high enough?

Ive looked at pricing for intercooler upgrades

Hpdiesel with fan $1295
Crosscountry with fan 1595

Anyone use these?

Dont waste your coin. The ZD is no power house mate. You wont see enough return for $$$. I was using a cheap $400 IC and running 25psi no issues. Put the money into a better scoop. The OEM scoops are just too low and dont catch enough air.

Which cheapie are good ones?

Ive seen plenty on fleabay

If you've got dawes right in surely you can hear the boost leak..
That thing woukd be humming..
If you can't hear the turbo or the squeal from the leak I'd be looking for a vacume leak on your actuator system..

When you start the car the turbo arm should lift straight up to the adjuster screw..

Dont go spending big $$$ on your IC as Mudski says its no power house, as quick as they are.
Things like a larger IC are a total waste of money,,money which could be spent elsewhere.
$500 should see you with a quality IC


Heres one for you tested to 60psi with 2 yrs warranty

Ive never seen the actuator rod move. Open and close the needle valve with motor idling and it doesnt move.

Cant hear any leaks.

You wont always hear a boost leak, its only 16 or so psi, plus with the engine noise going on it would be hard to hear.
To the op, test the intercooler first, then start from scratch with the dawes and needle valve setup. Otherwise you will just get yourself confused.

Hi Mark, i just sent you an email, do you have spare springs for the dawes valve, mine seemed a bit out of shape when i looked at it yesterday.

Cheers

Phil
