My experience is that most pollution controls help engine efficiency these
days, with the exception of EGR and the catalyst. These controls either
reduce the peak pressure (temperature) in the cylinder, or restrict exhaust,
so removing them should improve performance. Under no circumstances would I
remove the knock sensor!!

A proper carb setup will produce lots of power at the expense of lots of
pollution and fairly bad mileage - but if you want to GO, carbs are a
relatively cheap way to...but they have problems with altitude - you would
nned to re-jet if you are much higher or lower than where you initially set
them up. One place modern injection is MUCH better.

An outfit in California (C B Performance) makes a performance injection
system for air cooled engines that is supposed to scream - it includes a
control panel that the driver can tweak the engine from while driving. $$$.
