Piggyback performance chip for my Audi. I have a turbodiesel engine that was part of the VW/Audi emissions cheating scandal and after the EPA-approved emissions fix, it lost some oomph. This tricks the engine into putting out a little more boost, so it drives kind of like it did before the fix. I'm sure most of the settlement money was given to Jew lawyers, but I have them to thank again for a nice fat check from VW/Audi and also from Bosch. Because, as you know, I'm always looking for a handout.
