It's pretty significant. Like I said, you get an initial BARK, and then it settles down to warmed-up idle after ~1.5 seconds. I felt it useful/necessary when I had the Xtreme catback.How much of a difference did the cold start tune make? I'm moving and had Livernois send me that tune in case my new neighbors don't appreciate my exhaust like I do.
