Wastegate rattle and boost

I was curious if my wastegate rattle would cause a delay in boost. Driving my buddies 335i with the same mods his seems to react and get into boost quicker than mine does....so would my wastegate being loose cause that delay in boost response?

Yes. I noticed a huge improvement in boost response and targeting after adjusting my rattling WGs last Spring. Rear is easy, front not so much.

It's my rear that is super loose I've tried getting my wrench in there but can never seem to get it on the adjustment nut and haven't wanted to take my downpipes off
