Hey guys been lurking a while trying to read up and learn. Bought a 2010 SHO PP a month ago and it has 73k on it. I'm loving it so far! Very fast! Few questions. First it seems one of the previous owners installed an exhaust on it. I haven't had a chance to get under it yet to see if I can tell what kind. But I was wondering if someone had the knowhow to put an exhaust on did they maybe tune it too? Is there an way to tell if it's currently tuned? Can you tell the dif between the 2 and 3 bar map? Maybe I can at least check that? Other than that my other question would be Unleashed or Livernois? I like the simplicity of set and forget of LMS but like how Unleashed can dial it in from data logging even tho I'm not sure how to do that! Plus I like how Unleashed SCT tuners have the gauges. Also what's the dif between the Livewire and X4?
