I'm thinking about buying a diesel smart unit for my 2010 d22 has anyone on here had any experience with this brand. Iv been down the road with a fuel rail chip a lot of money down the crapper and a new fuel rail later. This time I want some thing with better and safer options. With the last chip and exhaust package, they only managed to squeezed out 106 hp at the wheels. Am I dreaming in expecting more. from what I can see about the diesel smart unit I'm surprised I haven't heard more about it  sounds like a great deal
