Hi guys

I've got a F30 from 2012 and its been a couple of months now that when I try to accelerate the rpms will stall and then jump up by 500.

When driving normal I don't feel any hesitations but as soon as I attempt to add some speed I feel like the car doesn't have the immediate burst of speed it used to have.

I must also add that I had the car tuned about a year ago.

Does anyone know what I should try to resolve this issue or what part is likely going bad?

Thanks a lot in advance.

SOLVED: Took in the car to my dealer and he changed my airfilter and put in a full bottle of fuel injector cleaner. Runs like an animal now!

Is it a bolt on tune or a flash tune? Put it back to stock to see if the tune caused the problem.

It was a flash tune

This is the B58 forum. You need to ask in the forum for your engine
