[QUOTE="JAJ, post: 15882015, member: 131874"] I remember having a smoothness problem with my 2011 Coyote 5.0 with a TVS on it, and to make sure there was no underlying issue, I locked the bypass open with a zip tie and took an easy drive around the neighborhood to see if there was hesitation or any other kind of rough running when the bypass wasn't opening and closing. My recollection is that it ran great - it was only when the bypass was closing or closed that I had the problem. I think I fixed it with a tuning change though (I have SCT Pro Racer). Sadly, I can't remember what I changed, although I can say for sure that I didn't change the bypass actuator. The thing is, from the point of view of the blower, your 5.2 isn't that different than your 2012 5.4. A little smaller displacement, a bit higher revving and a different cam, but otherwise it's just another engine. So look at the bypass setup on the 5.4 and see where it's set. If there's a difference, then maybe you're onto something. [/QUOTE]
