Thanks for your comments.
Took the induction air filter off and put the original back on, happy days ,it pulls like a train! It's now back to being the best 4x4xfar.
Is it possible to clean the induction filter efficiently?
I have a problem with lack of power at about 2500rpm. I''ve checked hoses, fuel lines and wastegate actuator and they seem ok. Also the fuel filter is one year old and has been checked.
Steady acceleration there's no problem, but give it a bootfull there's dark grey/black smoke and feels like I'm going backwards. Any ideas, cheers
