Hello friends, can anyone recommend a specialist who can tune a 3.8l xk engine to perfection? Preferably within hour of W2 London.

Any views on these?

Hello Moritz,

not a lot of response it seems?
Assuming the engine is in good repair with sound compression etc, then there is the option of having it tuned by conventional methods which should be straight forward using companies such as you link to.
The other option is to find a rolling road, ideally one who is familiar with older engines to really check the fuelling and timing. Note that as changing the fuelling also requires optimising the timing and may need both significant time expended and replacement needles and springs and adjustment\modification to the distributor.
The second option does offer a better result but may be disproportionately costly with regards to the gains over option one, that said if option two is used to get the best from what you have without modification then it will not neeed so much time on the rollers.

Not used them myself but have heard good things about Winspeed from Surrey JEC members if that helps.
