anybody got first hand facts and figures on the above, mpg, reliability, power etc, or would intercooling be better?
In order to answer your question, you need to know whether yours has a Bosch or Siemens fuel system.
(For identification, the Bosch has an in-tank lift pump, the Siemens a priming bulb under the bonnet).
