If I have 2 bmw e60 2.0D 163HP, one is stock, and one has DPF off , EGR off and something like 190HP, if i read the tuned one and compare the files from tunned with the stock one, and just modify what is different in maps between them, is enough ? And then obviously remove the DPF. Will the "stock" have the hp that the tunned one has?
Sorry if is a stupid question, I' ve never tunned a car and it's better to start with mine! :D :D :D
