Holden Captiva: Walkinshaw chip queries

...

I'm thinking of installing a Walkinshaw-modified ECM in my Captiva diesel. They are supposed to boost power and torque, but at what cost? What happens in regards to the particulate filter, because if they run hotter surely it would shorten the life of the filter, is the ECM set within a certain parameter regarding fuel/air mix etc? Are these units all they claim, or just a rip off?

I can't comment on the Walkinshaw chip specifically, I don't have any experience of it, but I'm not a huge fan of the chips in general as you don't really know how they achieve the results they claim, and ultimately you don't know what effect they will have on the car down the track. If you can find someone who has fitted a Walkinshaw chip you could ask them, after all first hand knowledge is the best you can get.
