Dyno tune or auto tune with PcV
Just like it says. I suspect my canned tune is not the best option for me. Debating on dyno or auto tune. Biggest thing is i am kicking around cams next winter. Here is what i have now.
103 with 9000 miles
SE ventilator Ac with K&N filter
Vance and Hines dresser duals
Vance and Hines double slash 4" rounds.
Doesnt apear to be getting a lot of low end torque. Mostly 2 up riding 240 rider 160 passenger.
Get some poping on shifts between 2-3 out of the rear head it sounds like

If you plan on making future changes, like the cams you mentioned, I would go the autotune route. Will get expensive to dyno every time you add a mod. With the autotune all you need is a base map that gets you close and you can dial it in from there yourself.

PcV with Autotune
PcV and Autotune will do you fine for the stage 1 you got now and into the future cams and any other changes or upgrades.
Note that when you go autotune, the initial tune you get, either through FuelMoto or Dynojet website is just the starting point, and the process is that you run the bike and do interative "Autotunes" which will dial it the best tune for your particular bike.
it's not one tune fits all off the shelf, like the old days with the PCIII.
There's a little bit of a learning curve on this, but it's worth it.

I've been through canned maps, autotune and dyno. Nothing beats a proper dyno tune. If ya are thinking about mods, try a few different stage 1 maps and get it dynoed when ya do the cams.

I was thinking I would go the auto tune now. Then yes do the cams, lifters, and rods later. Then have it dynoed with the auto tune to keep it running at its best after the dyno. I ride in all kinds of weather. This is the only year I didn't ride in the winter months. Bike was torn down all winter for major make over

Just my opinion. BUT, the auto tune feature is very limited in what it can do. That's because the only feedback item in the loop for auto tuning is the O2 content in the exhaust. That may help the fuel management. But it won't do much for making power where and when you want it. You need feedback on torque and hp across the rpm's and throttle positions to do that. With just the tuner you will be able to iron out some of the issues like heat, popping, and pinging that are common Harley EPA compliance kind of problems. So go ahead and get your tuner. But wait until you do all of your mods before you get a dyno tune.

As for Autotune PRO, it's more refined, accurate, and adjusts faster than the basic but if you're going to eventually have it dyno'd it's a waste. In my opinion.
