From TDI tuning
Do you think that would be possible with just a tuning box?
My dad had one of their boxes for his MK5 GT 170TDI, ran it 3 years with the box on. Took it to 200PS, not an extraordinary increase. Upped fuel economy by 10% too. This tuning box is all about the fuelling, does not do anything with the turbo operation like some other boxes do which are kicking out a reported 215PS.
I think upping by 55PS will be frowned upon by most insurers - some are mod friendly up to 20% power increase, but this one might up your insurance a lot.
