I have the PV. It simply is AN AWESOME TOOL!
The capabilities to tune the bike yourself, I just find too resisting.
There are numerous 'canned' tunes that come with the PV unit that, if you're running one of the tunes listed, you simply flash that tune to your ecm and off you go!
I bought the XL last year on a whim and it had already had the stage one stuff done to it but the kid had 2" Rush slip-ons on it that were just too loud for my tastes...and my neighbor's. ( BTW Ryan, at Rush, is a great guy to deal with! Thanks Ryan! )
So I took off the slip-ons and went back to the volkswagen sounding stock pipes.
Pfft.
But I did have a lot of fun dinking around with the PV tuner and tuning the bike. If you're lazy this is not for you-pay someone else to do it. Like Harley dealer who tuned the bike for the kid I bought my bike from-which showed temps reaching the 420s! BS! NOT GOOD!
I bought some Rush 1.5" baffles and put them in a couple of days ago.
Sounds like a Harley again and not TOO loud...but enough to let cages know you're in the vicinity. Good thing, that is.
I ran a log yesterday with the canned tune in the PV and checked it on MLV ( Mega Log Viewer ) and it showed that DynoJet had done there homework-the tune was ****.
No decel popping and plenty of pep.
I'm very happy with the PV.
Plus I use it, mounted on my handle bars as my VS and RPMs ( kid did one of those things where you mount the speedo below the tank-f'n stupid-unless you LIKE taking your eyes off the road )Also, on the same screen, I run fuel economy, VEs, tp, map. And many more options to choose from.
My vote is if you want to learn about how your engine is actually performing and why, get the PV.
If you just want to pay somebody to do it for you that's all good, too.

The real important part of your reply is "dyno by a pro"
i had the sert and had the dyno done at my dealer. always ran rich and had a dead spot on acceleration. they would tell me it was spot on. in rural new hampshire your choices of dyno stations are few and far between. upon replacing the sert with the thundermax the bike came alive. that is the real reason i like the thundermax. you don't have to rely on finding that pro tuner.

 

But can it do as well as a pro? I doubt I could tune PowerVision as well as say FuelMoto. I could probably, with a lot of time spent, come close. I suppose it has to depend on what you are willing to accept. I tend to find that in my life, little to nothing good has come easy and cheap. Certainly not in the long run. Every time I tried to save money and effort, I paid more in spades later.

 

X2 on the Power Vision. The bonus over the other tuners (talking real tuners, not piggy back devices) is quoted above.

 

Might just go with the V&H Fuelpak in the meantime. How big are they and WHERE do you hide them?
