I know in the car world, not many get dyno tuned and rely on hand held flashers with canned tunes usually with decent results.As long as you're happy that's what's important to me. I will say the exception doesn't make it true, but it is nice that your bike is running smooth!
Most people send things in blindy when someone has a large following and it appears they do so many, though. I won't say that's a great metric to base someone's quality, I'd look for customer reviews/testimonies of returning/needing remapping.
It may not be as highly tuned as it would be on a dyno but for what I use it for it's good.......
My bike was dyno tuned through the Bazzaz but it crapped out last year so I wanted something to get my bike running right again...and it is.
