320i sluggish ,any clues

Ok love my e91 2007 320i,but it seems sluggish upto 3.5-4k ,car runs and idles fine with 34mpg round town.It had a valvetronic motor issue so fitted a new one but now and again with the old motor fitted it would fly ,so performance is there…somewhere.Any ideas???

Intermittent misfire? Coils? Any fault codes?

no fault codes at all.when the valvetronic was playing up and it went to limp mode if I kept driving albeit at a slow pace ,after 4miles the car came to life and drove like a good one.Pulled like a train and was alot quicker??

Could try cleaning the VANOS solenoid a and putting them back in if you have not already.
