Is a new maf needed?

[woopyawass]

I would suggest starting with the things already listed in this thread mate.

Can you hear a boost leak?
Does the car run the same/better when you unplug the maf?
Can you feel it come on boost at ~2k rpm?

Welcome to the forum btw!

Thanks for the reply.... Maf sensor as ben's when disconnected goes back to standard power and no management lights!... Checked for leaks... None apparent ..egr been disconnected, plugged and mapped out of the system by pro Steve.. Replacement cone filter on, decat ... Straight thru just back box system! Seems semi unburnt fuel so would this mean my hdi needs more air? Is the maf sensor reading wrong??

Just want to say also ..... I know I'm a forum virgin as such!!hi to all
An always use good lube and please be gentle with me!
