Please do not think that this post is a diss because it's not, but my question is WHY? As in why did you buy this unit over a SERT. What does this unit do that a SERT dialed in by a knowledgeable tech doesn't ? I've read all of the posts above and I must be missing something, because the adjectives being used tend to be on the mild side. Why am I not seeing any superlatives here ? I've got a SERT and Reinharts on Elvis and I don't get any popping on decel. I get it on LD because LD has stock headpipes which allow cold air to run up the left side on decel. My understanding of that issue is that a properly tuned engine running true duals should not pop on decel. S'anyway, I'm just wondering you know, and seriously hope this post is not offensive.

A few things Brian. I'm accepting now that the unit is accurate. So it is accurate, all the time, constantly adjusting to be so, under all ambient and environmental circumstances. That is more than the stock system does.
It adjusts to changes. So if I get a wild hair to change pipes (as I'll need to in another year or so) the cost of those pipes won't be added on to by a new dyno tune to make sure I'm getting the best use of them. Put the change on, whatever it might be, go ride the bike a bit, and voila; retuned. No hundreds of dollars of repetitive dyno time.
To repeat the first one; it is accurate. Repeated for a different reason though. I'm lucky to have a great dyno guy right here. Most aren't though. We all know how average (at best) most of the tunes are. This system dials you in without having to worry about it.
There's more to getting it to accomplish all that of course. But the core of the gain is more measurement and accuracy provided than the stock system can supply and the (almost) automatic ease with which it's gained.
I may occasionally like to tinker with some occasional minor changes on the bike. I know, I know, you never touch yours and they stay as bone stock as the day you rode them home. But I occasionally tinker, just a little bit. But I'm also appreciative of being lazy when I can get away with it too. The autotuning capability allows me to be lazy. I can do the tinkering I might enjoy and the bike will take care of the rest.
Say, oh, for example, I put a Doherty PowerPacc on some hypothetical orange bike. I just knew by the feel that it made things better. But the only way I'd know I was fully taking advantage of how much better it might make things would be to add the cost of a dyno tune on to the cost of the air cleaner. With this I wouldn't even have to consider it.
