2012 FLHTCUSE7 bought in 2018 with 6700 miles. First change in 2018 was Fullsac DX headpipe with Kuryakyn crusher trident slip ons. TTS by Master tune and dyno tuned by Doc's Performance Tuning in Minneola FL. After exhaust bike made 82 max HP and 98 max torque. After TTS and dyno tune by Doc it made 93 max HP and 111 max torque
After dealing with the horrid valve train issues of the 110, stock SE 255 cam worn and cam bearings at 12K...replaced under my ESP, however to me that was not a long term reliable solution. Replaced the lifters out of a abundance of caution with way better S&S.
Yesterday Doc jammed in TTS 150 camshafts, replaced SE lifters with S&S lifters, replaced the 200 lb SE valve springs with T-Mann 160 lb beehive springs, Cometic .30 head gaskets and did a re-tune. After dyno tune yesterday she made 102 max HP and 116 max torque.
Engine is noticeably quieter and the power is certainly there. I was going for more reliability but definitely am very pleased with the HP and torque gains.
