Just a quick question browsing the forums and a was reading something about droning. I ve dona alot of stuff to my 7.3 and well when i was filling out the order form i forgot to put in a 6637 air filter. My turbo housing is 4 in and i delteted the ccv intake peace. cuz i forgot to mention this am i gonna have to send my chip right back when i receive it(ordered nov 10 and still dont have it) tell you what not having a chip since the end of oct really sucks, my fault though new parts old chip didnt work the php seemed to be what i needed so im hopeing its a badass product. anywase back to my question will an airfilter really make that big of difference or is it just the intake style? thanx guys

"Intake drone" is nothing to be concerned about (it's nonexistent) on a 7.3L.

You will not have to send the chip back because of the large cylindrical air filter. No changes necessary.
