So I took the Patrol out over the weekend to grab a few things at the shops and also give it a bit of a run. I did notice I can't make no more than 20psi boost pressure when I could easily make 30, and she's blowing more black smoke than usual (so it seems, might just be me on that bit).

So I've removed all silicone boost hoses cleaned and inspected them and decided I will change them out anyway. Intercooler looks spot on, and all hoses from the manifold to Injector pump and then to the boost controller are good. I will try to get a hold of another boost gauge just incase mine is playing up

If changing out the hoses doesn't work, and the boost gauge is reading right, what else should I be looking for? .

Cheers.
