Surely (well in my opinion anyway) a std cossie plenum aint spot on and gives more air to number three. And as a cossie on std type management gives the same amount of fuel to all cylinders, surely as the mixtures are different in each cylinder you are getting the same effect of one cylinder having more BHP than the others anyway???????

I wonder how much out the std system is with a lean mixture going to number 3 as described above???

I have got an EGT probe for each cylinder and T6 lets you do individual cylinder fueling, so surely having each cylinder running at the same temp and running a correct mixture is more important than any potential difference in power at any one cylinder?????

Just my opinion by the way.
