I have been told by the dealer that I don't need to tune my 2012 CVO Streetglide after adding the Freedom Duals and 4" Racing slip Ons.  The bike has increased torque and HP.  The bike is alot quicker than before the mod.  But what would be the best tuner to add?  Or would you add one to this set up?  I look forward to input from others that has already crossed this road!!!!!

Definitely get it dyno tuned.  You have many options, but the top two are the Dynojet and the SERT.

Your dealer is wrong.  With JUST slip on mufflers, you can get by without modification of the ECM tune, but if you changed the entire exhaust system out, which gets rid of the CAT, you need to get it tuned.  There are many options, but I am a fan of the TTS Mastertune, but basically you need to use whatever device your tuner is comfortable with.  You live in North Alabama, so I assume you are using either Rocket City or the new Natchez HD over near Florence.  Whichever dealer told you that it does not need to be tuned...avoid them because they don't know what they are talking about.  If that is Rocket City, I'm not at all surprised.  Natchez is under new ownership (used to be Foster's HD) so I have no comment on what kind of dealer they are, or what kind of service dept they have.  Very few HD dealerships have people who can actually tune a bike, even with HD's own product, the SESPT.  If you use the HD race tuner, be sure and get the one that is the PRO race tuner...there is a "street" version as well, and it will NOT do what you need to do.

The TTS is better, IMO, but both function in similar ways.  While devices like the Power Commander work well, they are a piggyback device.

Rod's Performance in Hanceville, Alabama is an authorized TTS tuner.  The only thing with Rod is that he is kind of old school and likes to tune the bike in open loop mode...just tell him that you want a map that still runs in closed loop in normal cruising ranges.

Well, maybe the top two after the TTS kit.

Definitely procure some equipment with which to recalibrate the ECM.  Don't waste time or money with any piggyback controllers.  The stock ECM calibration isn't going to be any better than "hardly close" to what you need now.  The ECM's adaptive routines will compensate some, but not nearly well enough.  And those routines are not intended for such use.  For one thing, the granularity is way too coarse and for another thing, you'll be wasting available headroom for the routines to do what they were actually designed and programmed for.  You want the ECM to be directly calibrated in such a manner that the adaptive routines are operating right in the center of their ranges.

Where are the 02 sensors located in that pipe?

You MUST tune. Dynojet Powervision and AutoTune. No dyno tune requiried, very easy.

Yea i know Rod  we were in the Army together before he retired!

they are located in the same location as stock.  Right behind right floor board!!!

Just talked to Rod and he said due to the heat in our area he said open would make the bike run cooler and take the O2 sensors out of play.  Your thouhgts!!!

What he says is true...running in open loop, he can add more fuel to make the bike run cooler.  It's also dependent on what fuel you are using at the time, etc.  However, by doing so, you are giving up MUCH of the functionality of the ECM and it's ability to adapt to variables like quality of fuel, etc.  There are more knowledgable people on here that can better describe all the things given up, but from my somewhat limited knowledge, it is ill advised to give up ALL closed loop functions and run open loop all the time.  By doing so, you are basically making your bike into a pre '07 model which had no O2 sensors at all.

Glenns, Doc1, Steve Cole, Steve George, etc can better give input on this subject, so you might want to start a thread on the Intake/Exhaust/ECM board to get a better response than I can provide.

Have to jump in & recommend Rod's for tuning.  He went the extra mile on my '00 SERG (no 02 sensors) & made it right before he would take a penny in payment.

Midnight, I think you said it well enough.

Thanks Mitch....the first run of his pipes the heated 02 sensors where up by the valves and then an adapter was made for the heated sensor to be placed in the large sensor port. I'm very pleased to hear they are in the right spot now.....I love their Classic Muffler with the quiet 88 decible baffle, it has a very rich, deep, rumble and you can still hear your radio while cruising. (plus they tune and perform great)

Doh!!  The older I get, the more the brain farts happen...   It's all those drugs things I experienced so many years ago...I have to let some of them go to make room, and it's not working out too well...
