I know LUK are pretty well known brand but what kind of power can you put them under?

 

I've seen people say once they remap higher than X amount.. they use stage 2/3 etc

 

I can get one of these from work for about £150 new.. there sitting on ebay for £350!!

 

What is the different from this one below and say... a Sachs one

Best people to speak to are the tech team at LUK, I used to speak to them a lot when I worked for unipart.
