Hey guys getting a fmic kit and just wondering what would a safe boost level be? I'm wanting to add a boost control once I install the fmic
How much boost is safe?

wouldn't bother increasing boost however a boost controller will help reduce wastegate creep and get boost up quicker.
I'd probably sure up the fuel delivery first, to be safe. Like Tweak'e said you should see a decent increase in linear power delivery by putting in a good quality boost controller.
I used to work at a performance mechanic workshop and that question would get asked so often, my answer was always safe boost is whatever the manufacturer sets it up at. Anything above that and it's a non-linear upward scale of unsafeness...lol

My Nav runs 15psi with the front mount.
Might chip it one day.
However a better turbo is going to be tried first.

What's the actual stock boost of the d22 zd30's?
afaik 15psi. give or take a bit for gauge error. with exhaust mods mine now peaks around 18psi. according to the manual the waste gate is set to 20psi.

Do you use a Dawes valve on the Nav's like the Patrol guys use to prevent over boosting?

Dont need to as they run a standard waste gate turbo.
Only the GU's need it because of the Variable van turbo.

OK, just learning about the ZD30 Patrol engine and wasn't aware of the differences.

I haven't read up on the CRD ZD30's for a while but I doubt the CRD's need the dawes valve.
I could be wrong though.

70000 lbs would be as high as i would go, Unless you run a Rolls Royce Trent 900. then you might want to check it for oil.
the crd patrols have a better control system so its not prone to overboosting. just like the D40 navara.
the non-CRD patrol has a fairly crappy control system, something that should have been ditched a long long time ago.
