As per previous post, am sure the 535's have twin turbo, specifically a smaller one added to give turbo at lower revs and avoid turbo lag.

I wonder if it needs a reset of kick-in if it is such a new car? It's on the forums here how to do it... I did it on mine and it worked a treat... I don't have the delay anymore in any mode (but in Sport+ I never had lag/delay)...

I think you will find after 2000 miles it will go away after your run-in.... it may be a control mechanism.... my car really opened up after 1500-200 miles and gets better each 1000 miles, smoother and more responsive
