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?
Have you checked the charge air pressure pipes from the turbo to inter cooler & intercooler to intake manifold? Also worth checking the intercooler for any obvious damage too
