if there is no efans or k&n it wont reall make a difference, it was just tuned that way to show the computer the increase in airflow, so you might not get as good of mpg increase, but you will still get some, plus the added horse and torque. the speedlimiter i dont believe was set on the new pcm. and yes id do 75.00 plus shipping

No you will still get the same increase. Jesse doesn't change anything for an intake. As long as the pcm is unlocked(like my wait4me tune was) it will work.
