Just Put in the Kwik filter yesterday. Took a bit of doing and had to visit the local hardmare for some plumbing, but she fits. I only got a bit of the whoosh, but hope to hear more. Haven't pulled a load yet, but I did sure notice more snap. trying to light up the tires in 4th. (DRW on gravel) Have come close. Third is no problem. Throttle response is right there. No waiting. It's all good.

yes i sometimes get the woosh constantly going uphill with no load. basically i only hear it if i let off the pedal fast or if it shifts. my truck is bone stock other then that and the red line unhooked. when it shifts, it actually rockets you back into the seats. our V-10 dually doesnt do that, same transmission. it actually shifts to a lower RPM going up hill, you can feel it rocket you forward.
