Hi chaps,

I recently bought a 306TD for SWMBO. It's a '97, but in decent nick, 2
prev owners and 81k miles. Anyway, it looks likely that it's going to be
the family runaround, with me doing a good chunk of the driving, so I'm
thinking of things to give it a bit more poke.
I previously had a 405 with the same lump, and had that fettled by a
company down in Leics somewhere - it made it quite a bit quicker, and I'd
happily go back there, except that I'm living up in Durham now, so I'm
wondering if anyone knows of anyone in the Durham/Tees/Stockton area or
anywhere up to the Tyne who might be able to provide similar fettlage[1],
preferably without instant engine borkage?

I know Abo lurks round these parts somewhere and may have Local
Knowledge, but any suggestions welcome.

If it's an XUD on a Bosch pump, remove the anti-tamper plug for the
mixture screw, then screw the adjuster half a turn in (or maybe out for
a bit of black-smoke-action (or a quarter of a turn for less smoke but
more oooomph...)

Indeed , but you really want to be re-setting the boost aneroid peg as well
as the max fuelling screw (mentioned above) for best results, and also
checking and subsequently adjusting the boost pressure.

I expect the wastegate spring has gone soft and you are not seeing the
original factory 1 bar. Start by getting that right, then adjust the
fuelling.

Tim..
