Hey Grumpy,
I am gonna be riding in the Ozarks this weekend. I haven't had but one very short ride since they were installed this week. My RamAir kit came in just before we left for the trip so it will go on the bike probably next weekend. At that point, I will see if HansO recommends a good tune to start with. I also have a shop close by for a Dyno run to see if we can tweak things a bit.I will keep you posted. I will say right off that this setup is at quite loud compared to stock but I prefer loud for safety reasons along with it sounding bad *ss. It drops the octave from a tenor to a baritone.
