I really dont want to argue about your test results.......but I will say we can
take advantage of the spacer with our MPI .
The way it works is this
The spacer ( say 3/4inch thick) has a volume to it. thus the air volume
introduced to the cylinder on intake stroke is increased....but the darn
computer dont know it cause the spacer volume is located after all censors do
there readings. so youget more air but the same fuel shot in by the
injector.(cause it dont know about the extra air) then on compression the
volume is greater so you get more compression which in turn fires that piston
down a little harder so (you go faster)
The fuel economy relly comes in to play because you have more power now so you
dont need to push down the go pedel as far to get the same output.
and finally the reason that your k&n's or whatever make the thing use more gas
is cause our old pal the computer knows your givving her more air and he
squirts in a little more gas to keep everything in check with programming.
Maybe you should try the dyno again?
Thanks for your time
