US-335D, DPF off and Ecotune tune and pipe
Does anyone have any experience with ECOTUNE out of Scotland that provides a DPF removal pipe and an ECU tune re-map on a US-spec 335D? They claim they've sold some to US customers and that the results are amazing... The major negative is that you have to physically remove your ECU and ship to their Scotland shop due to the encryption on 2009 and up models. How does this new tune and DPF removal affect the still present DEF system and urea process? On a side note, I live in an emissions exempt state for diesel vehicles. Any information/thoughts is much appreciated as I can't find much info regarding the DEF system after the DPF removal and re-map.
