hi all I seem to have a problem,

Now this could be completely normal but I doubt it as never experienced it before.

I installed a new defat full system recently and no boost doesn’t build till about 3.5k and when it hits around3.5 k it’s like a switch it hits hard there’s absolutely no gradual build up it just as if you flicked a switch.

I have replaced a few vaccume hoses mainly fuel pressure regular ones.

The lambnas are not plugged in ,there’s a very small exhaust leak from turbo side fixing it very soon!

Other than that theres 2 hoses that I’m looking at one is the one next the fpr nipple on the intake goes Into something infront of the intake .

The other well I have no idea what it is but I’ll attach a picture of it.

(Yes my engine has a (slight) oil leak new gaskets are on the way)

Thanks in advance any knowledge would be much appreciated

Unplugged boost gauge also but still nothing
