| I notice the same thing, but I thought it was just me. I too have a LLY w/ a Bully Dog Power Pup. I did a fuel filter & it got better, but not perfect. I have a stock airbox & stock exhaust so I hope it gets better when I can throw some more air at it and let it breath as well.
Let me know if you find a solution!
