Tuning the W204 320 CDI engine?

[ReggieGasket]

HI, I've just purchased the above car. As it's a big diesel I guess the engine can be chipped? Just wondering what the benefits might be?

The benefits are extra BHP and torque. The downsides (IMHO) are increased insurance, voided warranties, shorter engine life and lots of extra smoke. I expect Dieselman will be along soon to extoll the virtues of having an EGT gauge and he's right - all too many tuners just increase fuel and boost with no regard for EGT. I don't much care for 'chips' or tuning boxes and would much rather have a custom ECU map done by someone who knows that they're doing.

Thanks for that. I must say I'm not finding the car lacking in power. I guess I'm interested in the engine running better in terms of response and efficiency. I do put my foot down every now and again too
