I have a 110ps mk 2.5 which has being low on power for a while now.. 2 months ago the Dpf was removed and ecu reconfigured and I had a turbo boost leak that is now fixed.. and still no power increase..
Iv had the turbo looked at and being told it's worn but it's fine.. then today have bein told it gone by a different mechanic..
I don't think its gone as there was no smoke or anything like that and I feel that there is too much power at 4k revs to be go gone..
Anyone any recommendations on wah to do now?? I don't want to pay for a new turbo and that if it isn't gone..
Other things are
140k miles on clock
Air filter checked and fine

Thanks for any help that can be given..

 

Also I had the egr checked and was told it's one of the cleanest he's seen.. Air sensor has bein changed.. the problem properly started since the timin was done now that I think about it.. it feels like the turbo isn't boosting until over 3-4k revs..
