duncan, Why not switch to a 100 % fuel rather than playing limbo with differant mixes. You cant be getting an accurate mix without using weight. If i was you i would either go 100% e85 or use a good race gas.
After using the motec stuff i would go all out for that with as much of the sensor kit as santa can buy.

Only limited by the injector size limit Scott else I would go 100% now.
The current 850 cc injectors are at 95% IDC with a 20% mix and I dont want to push it more than that really.
A new ecu, bigger injectors and a 5th injector will help out with the extra fueling needed - these are on their way and will be in place for 2009 season.
It is pretty forgiving stuff though from a mixture point of view, certainly more so than methanol and from what i have seen, has good improvements.
As east anglia is well served by this fuel, it would be a shame not to use it.
If you get an extra injector stick it pre turbo trust me
