pulsing drone from 80mm BBK?
Recently I've upgraded to an 80mm bbk. Now I've noticed that when on cruise control at 65 or 70 I have thus pulsing drone sound similar to what an aftermarket intake makes. This will make the pulsing drone sound a bout 3-5 pulses and then quite and come back maybe in a min or so. Sometimes sooner or longer. Anyone have a similar experience with a larger throttle body?

It's hard to say there's anything wrong with that.. If your AC is running while cruising then that will cause a cycling "moan" type sound as the compressor loads and unloads the motor...
See what happens with all accessories off while cruising on a good flat stretch of ground.. Even when heading up a hill you could get a sound like that, which is normal..

Only thing that's leading me to think it'd the TB is it wasn't doing it before. Not necessarily saying anything wrong, just don't like the new sounds. I'm gonna contact PHP and see what they have to say. A custom tune can fix the drone from an aftermarket intake maybe the can fix this one haha
