Not so much Im guessing. I would advise to inspect (best way is smoke test) all hoses on the boost circuit (especially check under inlet manifold).

And for other error code, I would advise the n249/n112 delete.

n249 has already been done. and had the car snoke tested a few months back and it revealed nothing at all( had this issue a long while now)

n249 deleted has been done. had the car smoke tested a few months ago and it revealed nothing. (had this issue a while now ). dump valve was also tested at the time

second code i wouldnt worry about, get it mapped out.

first code could be a boost leak, but also ive read there is a bug in the original map of the car and a remap brings this to the surface (if its been done).
