Ok.... so, I decided to mess with the AFC today and cut back zero boost fueling as much as I possibly could.
If one flips over the AFC top and looks at where the afc lever hits the housing itself..... Right there the housing can be ground back at least a 1/4".
IMPORTANT FUTURE NOTE: .157" is the diameter of the stock slide pin..... a 5/32" drill bit is .15625"..... close enough .
Doing the above, my new slide pin is a full 1/4" longer than the longer slide pin that I sell on the site. Or 1/4" + .5mm longer than stock.
Result.... it helped, but it is still not anywhere near enough for my heap.
