Non turbo and you only got 43mpg? Wow, maybe the HDi isn't so bad then!!
The smoke test fail was nothing to do with the engine itslef, it was that daft chip.
For the EGR valve, you want to add the blank as well. Unplugging it is fine if the system is working, but if the EGR is already leaking, unplugging wont make a difference, you need to add a blank where it meets the inlet pipe for best effect.

This is a good point, not just the size, but the tyre type as well. Proxes and rainsports both lost me a few mpg over things like P6000s and Goodyear NCT 5s. But personally I'd rather have grip than an extra few MPG though lol.
