    What you are seeing is normal. Its shit, but normal.
    Instead of mucking around with the VNT grub screw and never getting it right, get yourself a manual boost controller (Dawes or Tillix), and a needle valve (does the same thing as adjusting the grub screw but much easier to do) Contact @Avo here. I know he have a Dawes and needle valve he wants to sell off thats never been used.
    In a nutshell, the Dawes will simply limit your boost level, say 18psi. The needle valve allows you to adjust and control how fast the turbo will spool up. Then say good bye to those bouncy boost levels...

    got me buggered why you guys with zd30s don,t convert your vacuum set up which causes all the bullsh-t , blown pistons, cracked heads, limp mode,ect,ect easy to convert to boost using the same bracket on the turbo, i used a boost rising arm accuator from a ford supercharger or MALES in melb have then for $125 they have 2 nipples vac or boost either one raises the arm i cut the adj arm from the old unit, made sure it was 90mm long from the base to the top of the adjuster then carefully welded it to the new accuator arm, threw in a boost controller ,set it to 18lb and guess what i have never had a single problem since, i can blow the doors off a factory td42 turbo with a few mods, my truck is auto and it pulls like a v/8, bottom end is so much stronger , untill i did this mod i was about to sell it, as i had enough of it and months of drama, truck of the road ect ect , now i love it and will keep it until cancer gets it

    A Vacuum controlled turbo on the ZD30 is the cause of cracked heads and blown pistons? Why did I not pick up on this earlier?
