After taking a good look at the MAF sensor and unplugging it and trying to downshift and quickly accelerate a few times it doesn't seem to be the source of the problem. Any ideas would be very much appreciated.

Hi. I own a Citroen C5 HDI 2002 110HP. I bought it about 4 months ago and the problem is whenever I downshift from let's say 4th to 3rd to overtake the turbo only responds at around 3000 to 4000 RPM but on a gradual aceleration 1st gear 2nd 3rd etc you can always feel the turbo starting to push the car faster at 2000RPM. This has put me in a couple of awkward situations like there's a car on the opposite lane and I'm about to overtake someone(I have more than enough room to do it without any danger) but then suddenly when I put in 3rd to overtake the turbo won't respond it will just accelerate like it has no turbo and I end up having to brake and get back to my lane. Thank you in advance for any help you could give me P.S: I'm about to go take a look at the MAF sensor to see if it could be causing this problem
