Huh?
An auto-tune system is only as good as the base map...........if you are using a canned base map then it's not going to perform as well as it could. You still need to get a base map done on a dyno with an auto-tune system so it can perform, all bikes are different and canned base maps are just that.
I would go with the TTS. In the hands of a competent tuner it will make your bike run it's best. That way the bike is tuned for exactly how your bike runs........not some other bike like a canned map.

If you don't know about the PCV, why did you say "Definitely TTS" in your first paragraph? You speak about dyno tuning and who's good where, but with the PCV-AT you don't need to dyno tune. That's the problem with this thread an others like it, as the PCV-AT has only been on the market for five months and few outside of those who've purchased and used it understand how it works. This will change in time, I think.

This is totally FALSE and is a good example of the problem with this thread and others, that few understand how AT works. You can put any map in the PCV, even a zeroed map, and it will auto-tune in a very short period of time. Of course a more accurate map will auto-tune more quickly.
Wrong, wrong, wrong! Go research this device first before making statements like this, please!

How do you know what fuel amount is need at a given throttle position at a given RPM with any given motor combination? A canned base map has no clue what is in your bike, what your bike needs, or anything. It's just a generic map that is going to get people going and off to a close start. If you want your bike to perform at it's maximum potential, then you will need to have your basemap done on a dyno so the system can then make adjustments to correct for changes in atmosphere and altitude.
What about timing?

Its simple the PCV adds and subtracts fuel to your stock ECM. It does have and timing adjustment like the PCIII. The TTS you are able to adjust and dial in many areas
1) AFR Table
2)Closed loob Bias
3)Volumetric Efficiency
4)Adaptive Fuel control
5)Power Enrichment
6)Acceleration Enrichment
7)decel Enleanment
8)Spark tables
9)Knock Retard
10) Way better Heat Managment then Harley
11)Spark Temp control
12) speedo Calibration for tire size and gear size changes
13) Red Line
And a whole lot of other features that you will never use

I install pc5 last week,and I download map from powercommander,the bike run great,just out of curiosity I went to make a dyno run just to check the air fuel mixture, the map was 98% right on the money,there was a two spots just a hair of and tuner was cool enough to teal me how to fix to perfect condition.
Can not be more happy with my pc5.
by the way this is my second powercommander that I own I use to have a pcIII on my warrior also very happy, no problem at all.
good luck with your decision.

Then I suggest you call and talk to people who know what they are talking about, because you have some serious misconceptions about what an auto-tune system does.
How do you know what fuel amount is need at a given throttle position at a given RPM with any given motor combination? A canned base map has no clue what is in your bike, what your bike needs, or anything. It's just a generic map that is going to get people going and off to a close start.

PCV does allow user control of timing and the autotune uses wideband O2 sensors and will correct your fuel map while you ride.
After talking with them, seems like a no-brainer.

No advise on the PCV, had 2 PCIII, and got kick back and back fire on start ups on both.
Why woud you want to add another piggy back computer to the factory computer you already have? Use TTS an adjust the one you have. In a previous thread they stated they installed the pcv, installed a can map and it dynoed great. Use the tts, install a caned map and no worries about a piggy back add on computer. The factory computer will adjust fuel but just in a narrower band.
With TTS Master Tune you have the same ability to adjust any thing in you ecm as you Harley Dealer.
