Thanks for that info Sibster
thought the mod i did might not be enough...

Do you know the reason why they use 90% valve duty?

can't picture what you're saying about your valve mods
Do you have some pics of the parts to explain
and a price please

I don't know anyone with a milling machine, can you get it done?

does normal idling suffer when the valve is heavily modified?
I thought of using 2 valves in parallel, one standard and one heavily modified that's only brought in when the ALS is enabled, would that work?
