emissions

so I am expecting to become the proud new owner of T6 kombi 204, or rather I was expecting to have it already, but am being told that the registration is being delayed by the VCA because it is awaiting certification confirming it is exempt under the new WLTP regs. Has anyone else had this...

Now all the companies who other re-mapping, claim improved mpg, but has anyone experienced it? Come on, be honest.
