Two 135 engine builds in progress, 21 RGS, 24 CVO RGST.
Khrome Werks Outlaw 2-1 exhaust for both, as well as the SE Wedge air filter, 68mm TB, and 6.8 injectors.
My 24 CVO is actually built/running. However, after being tuned by my closest Harley dealer with the SE Smart Tune Pro wideband kit, it runs worse than it did with the SE base map and narrowband O2's! The only other change from the SE 135 base kit, was the addition of the SE Extreme CNC ported intake.
Based on info learned from HD Forums, I've selected Central Texas Harley Davidson in Round Rock to take care of these shortcomings, and they are picking up my bike next Tuesday. Possible changes may include the Impact Wiring Solutions ECU, as well as trying currently available exhaust baffles.
All Makes Cycle Repair in Killeen, TX, has my 21 RGS.
S&S engine case.
Suburban Speed 135 Man of War Stroker Kit.
T-Man Pro Street (round intake port) 95cc combustion chamber heads, targeted compression = 11:6 +/- a tenth.
CR-557 cam.
V-Twin Powersports intake.
TTS tuner/SE wideband kit.
New CryoHeat Loaded, Harley Davidson Transmission.
2024 CVO ST transmission output 30 tooth sprocket/belt.
Should be an interesting comparison once the results are in!
Strange about your 21 RGS is I think what your tuning with is the best combo for tuning yet on FB he posted about how he prefers the PV or IWS. I politely explained why I believed the TTS and SE broadband set up is superior. He deleted my comments, kinda like the guy in Florida will do if you question his opinion. On you tube he goes by Finley Gambrel. I like some of his posting but have to disagree with some of his thoughts on tuning. He likes to tune by ear instead of trusting the data? I wish he was open to listening to other peoples opinions and thoughts. When done tuning yours hopefully he removes the SE module and reinstalls the narrowbands, enabling adaptive fueling. Tuned quite a few that way and it works awesome. Looking forward to results of both builds. On the other bike just be aware that while the IWS has some nice features your RDRS will not work. You can use the SE kit from the CVO on the RGS as they don't marry to the bike.

You've got my attention and I'm open to explanations if you care to elaborate, because most of my high-performance tuning experience is with carbureted engines on the very old SuperFlow 901 Dyno with Windyn data acquisition.
The RGS also has a PV license because the last time it was on a dyno, the tuner in Dallas didn't want to use the TTS, even though he advertised having the ability to tune with it on his website. Turns out that although he was able to make a smooth HP/TQ curve with PV on the dyno printout, the part throttle rideability and overheating absolutely sucked on the street and it didn't last, so add another tuner to the never use again list!
All Makes Cycle Repair liked the combination of parts that I already had and was the only independent shop that I talked to willing to use customer supplied parts which also include the Evolution Industries complete clutch basket assy, black ops comp ramp and diaphragm spring kit.
I'll now have to consider a TTS for my CVO since I didn't know that RDRS is non-functional with the IWS.

https://www.facebook.com/share/v/1FidmvSijy/Thanks, I'm not trying to bad mouth him, I just found it odd. I've been doing this since 2009 and still learn every day. I've used them all but the Fuel Pak. For many years I've only used the TTS.
Edit, Don't know why that link doesn't work, sorry. PM sent

CTHD emailed the CVO SE 135 results and will ship the bike back to my dealer on Thursday. The arriving graph is with the SE tuner and the final is with the Impact Wiring Solutions ECU. I'm calling it a solid 161 HP due to the weird (165) blip that the dyno captured at the end of the pull. I'll update with a ride report next weekend.
