After driving the my c-class for a month in S mode the pickup now is really nice. I love the sound of the xpipe even more as the rev really stays on the high side longer. Now I want even more and was thinking of having a engine tune but I do not know where to find one locally. Shipping the ecu is out of the question. If anyone in vancouver ever tuned their pre-face lift c300 what was the gain and how does it compare with the S mode?
