Picked up my 07SERK tonight w/Rinehart's+Thundermax Autotune+K&N Filter+lot's of chrome bolts on board. I was only able to ride off the trailer to the garage, so not a lot of time to let the Autotune do it's thing (lot's of ice (and salt!) still on the ground in Baltimore), but man - do those Rinehart's sing! I have a 06FLHRCI (RKC)w/Rinehart's+Thundermax+Arlen Ness Big Sucka, which sounds great (this is for sale - cheap plug), but the SE110 really makes the Rinehart's purr (just a tad more arsh in this beast). After a few more miles the RH's will burn in and the sound will only improve, as noticed from the 06. All my work was done by Allen Brown (Browns V-Twin, Westminister, MD). No problems with the Rinehart install re: O2 sensor fit. Allen actually called BUB to explain his "fix". I will post my dyno sheets in a while. Allen is doing some testing of the autotune, rather, I will be doing some testing. He wants me to bring the scoot back in after I put some miles on to see if the Autotune dial's in the dyno. He intentionally left a "dip" in the tune (around 3300RPM). I will post both of these sheets after I go back for the second dyno. Right now I am at 91.15 Max HP and 110.34 Max Torque. It's going to be 52 on Thursday and hopefully the rain coming tonight will wash away the salt so I can get to work on tuning!
