I have a 2002 406 sv D9 II sedan (auto - not much choice there!) and find it sluggish 'off the line'. It is a strong motor most of the time but being an auto doesn't help.
The used car dealer (!) said some people put extractors on them for more sizzle and a mate suggests 'chipping' it (I think that means a different engine management chip). Does anyone have any experiences / advice and, if so, who in Sydney can do such mods? Any way to re-programme the auto?
I don't want it to drink anymore high octane fuel than it already does, if I am normally gentle on it. Would extractors mean more noise?
