I've searched a bit on the forum, couldn't find anything that was similar to what I'm seeing.

I've got a 2000 ZD30. New motor, new turbo, new nearly everything except exhaust...

I have NADS all set up.

Issue: I have my dawes valve setup for 14PSI. I had my needle valve inside but it didn't seem to be working, I've put it under the bonnet.
I can't seem to get the needle vale right, it'll overboost, so I'll start turning it, but by the time I've got it down enough to stop overboosting, the spool up is way too slow and I start getting high EGT's just speeding up on flat...

It seems to be overboosting too easily though. I can be in 4th accelerating up a hill and it'll be doing 12-13PSI while I'm at 2700RPM, then overboost. It's even done it after I was past 3000RPM...

How is 12PSI @ 2700RPM overboosting?

Or am I missing something?
