Hey there I have an '07 335i with JB4 and I'm have two issues (besides waste gate rattle...)

1:In WOT or any heavy acceleration it throws me into a momentary limp from P0456 small evap leak code then goes away.

2: JB4 gauge highjack says that i'm on constant 100% vacuum whether its on gas or oil temp, tried resting gauges too.

So my questions are:

A: Is there a good fix diagnosis for the p0456 code and is it correlated to the boost gauge issue?

B: My car feels pretty quick like it has boost but I haven't had it long, so idk do I really have 0 boost psi and 100% vacuum? is there an easy way to tell? what could be causing this gauge issues if I am getting boost?

Thank you!!!
