Thinking About a Tuner
I know my bike has Reinhardt slipons. Not sure what if anything else has been done to it. My overall goal is better fuel mileage with the ability to upgrade as I go. Ive been looking at the pcv with auto tune as well as the power vision. Any recommendations as to either or something else? Bike is a 18 flhtk ultra limited.
thank you

If your goal is mileage, you should look at getting a PowerVision tuner, and then a live dyno tune. Put some Fuel Moto insert baffles in those Rinehart slip-ons. Lose the CC in the headpipe, if you have not already.

Thanks for the response. Are the inserts to make up back pressure after removing the CC? Also which tuner would you recommend of the ones offered? I see one that works off your phone, another with a small lcd and one for 700 with all the bells and whistles. Thanks again

Give FuelMoto a call.... they are really excited about the new PowerVision3 and its capabilities...
I have two PowerVision tuners (yeah two of them, long story)... and I love them... But I also have an auto tune pro module I use on my 2003 EFI bike that doesn't have OEM O2 sensors... So I NEED the PowerVision tuner to use the auto tune pro module... Plus I like to use the quick tune feature for some issues... like decel popping...
Other than those two things, they aren't really all that different.... and the PowerVision3 will save you $310.00.....
I don't know much about the PowerVision4, but I am old school... I don't use my phone for anything other than making calls, sending texts, and an occasional picture... so anything requiring you to use your phone or download a phone app is a non-starter for me...

I have a Power Vision on my Cross Bones and will be using a new license to run it on the Street Glide too. FuelMoto will provide incredible customer service and get you the tuner you need for your bike. The PV is great because you can adjust on the fly without a computer.

Yes, a lot has happened.... fairly recently...
The original PowerVision tuner, due to covid parts availability, has jumped in price to almost $800.....
They introduced the PowerVision3 & PowerVision4 recently...
The trend these days is everything done via cell phone and all info from the cloud.... The PowerVision4 is aimed directly at those customers... The PowerVision3 is in the middle between the two..
Jaime had a video or two about the changes, maybe still on FuelMoto web site, and they seem to be excited about the possibilities with the new tuners...
The chart I posted shows the differences between them...

Mostly to make up for the loss of backpressure with the addition of the Rineharts. I have them as well.

Someone correct me if I am wrong but in my experience a tuner is used to richen the fuel mix for more power and to run cooler. Richer mix means lower mileage and bigger smiles.
I did tell my indy that I spend most of my commute with the cruise on around 70 so on the dyno he leaned it out a little in that rpm range but gave me power everywhere else. Mileage went down a couple of mpg's but it runs fantastic.

A tuner does more than just correct fuel mixture. Theres the whole lean is mean, but not for long discussion but I think you already know that.
A good tuner can add/remove fuel where needed. It can optimize spark timing. It can optimize throttle position and so on.
If a fuel ratio is off or lean, yes richening it up will use more fuel, but youll also have more efficient power, hence .you simply may not twist the throttle as hard or as far.
Fuel, is also used to cool the top of the piston and its pretty well documented that heat is the enemy of any internal combustion engine.
Theres a helluva lot more details and science behind it thats really 30K foot view kinda stuff.
