Do any of you have any tips/tricks to increase the performance of a 1999 C180? I wanted a C250TD and was going to get it chipped, but decided to save some money and get a C180 for the time being and save up for a new shape C220 or C270CDi. Whilst I am very happy with my first Mercedes car, I sometimes wish it had a bit more oomph! Especially after driving my dads E320CDi wow what a motor!, and a friends E240. I am not a speed freak, I had a Merc Vito 112CDi van for three years and was pleased with the performance. I just like my cars and wondered if there were any easy and cheap ways to tweak these engines. I don't think there are any chips available for the C180, unless anybody can tell me different. Have already got a K&N filter which made a huge difference. Can anybody suggest anything else?
