Thanks for all the suggestions, just to add to the airbox theory.
I've been though all the airbox mods! From the stock setup, then the moded box,
then removed the air box fender resonator, now an open air cone filter setup.
My mileage hasn't changed with air filter housing changes.
My next move will be the injectors and the o-rings.
That's the only thing left that I can think of, because if you see all my threads,
you will know most everything is new.
