slp exhaust sound?

[DirtyMoney12]

ok figured I would start a new thread I just did the slp resonator delete and I decided to do the slp loudmouth 2 muffler. sounds killer I think but was thinking it may need tuned or a programmer? truck sounds really good but I get a certain tone or noise when slowly or lightly getting into the throttle at like cruising speeds? almost could sound like a miss when driving n then clears up when you hit it harder. im a mechanic n I know what a miss is but its not exactly a miss its almost like its a loss of power kind of thing? any suggestions would be great thanks!!

Could be your DOD.

Sounds exactly like cylinder deactivation. Switch to the instant fuel economy page in the DIC and see if it happens when it switches from V8 to V4.
