Hi folks, so having purchased my first Audi ever, an 2007 a4 sline special edition quattro 170 diesel, its had cambelt waterpump done at time of sale, replacement injector and a 1.9d bolt replacement or something but it looks as tho its had a remap in the past as its got a blank on egr and dpf weld looks like its been done after removal according to mechanic I purchased off. Not to mention car feels quicker than my BMW 330d I had previously. Question is how much power is this thing generating off a guess according to what's most likely been done. Car is rapid.
