Hi everyone.
I've been wondering if there would be any benefit in me advancing the timing on my Windsor a fraction. I always run it on 95 RON or better and since they were mapped for 91 RON is it worth it?

There are definite benefits of advancing the timing, more power, better acceleration and a better burn. You can probably advance it 4 degrees without any chance of pinging if you run good fuel.

as EDXR8 said, the benefits are there. I did it on my old XR8 from 25deg. BTDC to about 32deg BTDC and noticed a good improvement down low in the torque department. Essentially its best to use PULP but it will run ULP on occasions if needed.

Well, today I advanced the Mont from 30 degrees to 34 degrees, then took it for a spin. Still no pinging at all, I am running PULP and always do.
Didn't notice a big difference when taking off from a standstill, but you can definately notice it when you're doing about 45kph then boot it, kicks down and there is more urge there.

Ive advanced my EL a fair bit and the car has started surging something shocking (its an I6 btw). Just would stall out, idle violently, revs jump around everywhere, the engine would run HOT (but the temp gauge stays the same. Its weird :/

what could be done to an XF 4.1 carby (auto) in the way of advancing from the (i think 10 degrees) without changing from normal unleaded? would there be any point advancing on this or would i be wasting time and possibly petrol?
