Experience with chip tuning?
 

Hi,

Has anyone had any experience with those plug and play chips?
In my case it will be for a 2004 3.0d.
Something like this:

Thanks in advance for your answers.

I have used a few over the years, the best one for me is the Brabus on my Mercs and the CRD2 and CRDT+ from here...

Some just over fuel, some adjust fuel and boost pressure, some do fuel, boost pressure and injectors etc.

I have had better results from boxes than remaps, but only when it does boost too.

The one you link to is well regarded, certainly their top model anyway.

I have the DTUK CRD-t+ and there Pedal Box on my 2007 X3 3.0sd.
It makes a huge difference and is useful as you can turn them off without removing them.
