Ok so i just brought a 2006 zd30tddi manual 355000ks stock as a rock bar from bull bar and snorkel.
I have fitted boost and egt gauges but having trouble with boost or so I think so.
Here's what's happing,
First and second gear no problems with boost nice and smooth and holds around 15/18 psi
Third gear will go 10 psi then drop to 3 psi then will stay there for a bit then it will go to 15 psi and then I feel a jerk then goes straight back down to 3 or even 0 psi
Pretty much the same with forth an fifth
Is this normal for a vnt turbo
Help would be much appreciated
