Thanks John I will take it to the garage and ask them to check the re circulation valve 👍

It was a few weeks after the map I noticed it. I put my foot down on m62 a bit after slowing down for traffic and the boost was like taking off in a plane in 5th gear then went back to normal. After that I noticed a flat spot in the top 3gears. Its going back to the same guy that did the map to delete my dpf and map again.

It's a 30tdi quattro. I've had the car remapped miltek cat back and k&n. Under full load in 1st 2nd and 3rd it pulls like feck. But 4th 5th and 6th gear there is a noticable flat spot at about 4000rpm. Has anyone else had this problem. I've no dash lights on to say there is a problem.
