I refuse to do deletes, just won't get involved in it. If the tune is suitable there is no reason to get rid of them in reality,

I get asked all the time for removals, my answer is simple, either the car is not being used as intended, or has a mechanical problem causing smoke which is blocking the DPF. Low and behold, most come back once they have found someone to do a delete, cars smoking like a pig, guess why the DPF was blocked

Its easy to tell cars that have had a removal done in most cases, if you tap the filter, they go "clang clang clang" rather than "thud thud thud"
