Installed on my 2015 SG last Fri, rained most of the week but got a few rides in and couldn't be happier. Used the Hi Output slipons w/ Power Duals, Std baffle map (suggested by CFR) and it runs great. Maybe just a little stutter off the line but really moves after that. I may try the Twin Slash Rounds w/ Power Duals map (suggested by V&H) I haven't run the auto tune yet, I'll ride this for a few weeks then maybe try auto tune. The CFRs really sound good.
