Timing advance mod - garages near Beds/Bucks who can do?

[Cyder]

I'm thinking I'd quite like the timing advance mod for the freebie 'extra bhp' but I don't have the kit and although I'm confident messing around with most of the car, timing is a bit witchcrafty for me.

Can anyone recommend me a garage around the Beds/Bucks/NW Herts area that can do the mod for a reasonable fee? I'd rather it go to someone who has a vague idea of what they're doing!

Thanks.

Timing should be bread and butter for pretty much any garage. I'd suggest just printing the MX5Nutz guide off and popping along to your favourite local mechanic and letting him loose on it.

As above. No specialist knowledge is needed at all. I do it myself using an ancient (20+ years old) strobe.

Get them to replace the Cam sensor O ring while they are doing it otherwise it will probably start leaking oil from there which will eventually make a hole in the coolant hose beneath it causing you to vanish in an impressive cloud of steam one day soon
