320d feels flat
Noticed the last couple of months my 320d seems quite flat.
It’s low down in the Rev range around 1,500-2,000 I really have to put my foot down to get it moving.
It’s been mapped to 207bhp and had an egr delete kit. It’s also had new maf sensor about 1,500 miles ago.
It just seems really hesitant low down.
I’ve noticed with the window down when the boost kicks in there is a really loud distinct hissing noise. Now I know it’s normal to hear the turbo spooling but this is loud.
Turbo was reconditioned at 70k, it’s on 150k now.
Any ideas?
