It made a massive difference replacing the air filters, I also took the carbonio tube off for the timebeing, not sure if its better on or off due to the cold air feed?

The old filter was absolutely wrecked.

It still doesnt run as quick as his did and they were both agu w reg and his has like 40k more miles!

Whats the most cost effective way about improving this after the old filter was abosl*tely trashed?

Maf? Vac leakes? how much?
How can I tell if the turbo is completely FUBAR?

cheap air filters will wreck your turbo, if I were you I would put your airbox back in with a decent panel filter.

You need to start at the basics, when was it last serviced, check the plugs and oil etc, replace both if needed and then look for split boost pipes / leaks, clean the TB as people have said etc

Car was serviced in October and all those were replaced, fuel filter premium plugs oil etc, full service.

I have cleaned the TB and checked for leaks splits etc and there are none.

I have ran a diagnostic.

The air filter before hand was absolutely destroyed. https://drive.google.com/file/d/0Bzp7EGsjGffNVkx5NmNEX011NTg/view?usp=sharing

I have since removed my carbonio and just using http://www.ebay.co.uk/itm/Universal-Car-Air-Filter-Induction-Kit-Sports-Car-Cone-Air-Filter-Chrome-Finish-/301230360246?pt=LH_DefaultDomain_3&hash=item4622ba86b6 and its doing the job.

Reducing the size if my blue vac hose to my DV seems to have made a difference along with super unleaded.
