Didn't get your reply  :huh:

Cleaning it normally does more harm than good.  Wait for someone else to confirm what I think, that the MAF is reading low before splashing the cash  :smiley:

For reference though I logged an A4 on the weekend running 190bhp and his MAF was showing above 150mgs

Approx 6000rpm which is around where your peak power is anyway

not that i dont trust you but........... i dont trust you  :laugh:
nah ill wait to see what anyone else says but was thinkin either:
       
        if its regestering less air going in should it put less petrol in
or
        if the lambda thinks theres more air going it it will put more fuel in  :huh:

or could still be more to it than that!!!!

also i got a maf for a v5 (3") can i use the sensor out of it to test???
