I would say get a Bosch pump but out of interest, I asked a good friend that used to be on here all the time and answered these kind of questions. His answer below:
The more you turn the more fuel it will use. By the sounds of how far you've turned the fuel up, I would bet it's smoking. smoking is wasted fuel.
What turbo have you got and what is it boosting at?
You could probably more out of it with more economy.
With the MPG thing, I drive a 205 with a XUD, standard k14 turbo (wastegate adjusted) and Bosch pump (wound up and with some mods).
I got 45mpg last time checked and this was a few hundred mile trip from east to west with slightly spirited driving.
