Don't write angry. Your terse response didn't do anyone any good. A full detailed description of what is possible through the Diablo Tuner would have been far more helpful.
I think there is some legitimate criticism of the Diablo Tuner, they include:
First it is a handheld unit and it is expensive. Depending upon the actual handheld unit purchased prices range from $400.00-600.00 This pushes the cost of a factory computer from about $1600.00 - $1700.00 to over 2K. At that price your are greatly exceeding the cost of MS3 and fast approaching the cost of a FAST setup.
Second, I dispute your full control comment. According to Diablo own website while you can move shift points and the rev limited you are limited to a maximum increase of 600 RPM for both shift points and rpm limiter. This doesn't sound exactly like full control to me. Can you eliminate the rev limiter or set it at 8K? Do you full control of fuel maps? Or are you limited to selecting from a set of preconfigured tunes? Do you full control over spark maps? Loading custom tunes is great, but can the end user create their own custom maps? Telling a customer they have full control when the full control is actually in the hands of a custom tuner is not really helpful or truthful.
Third, Diablo and the factory computer does not and cannot support a variety of parameters that high performance users might find useful. For example, MS 3 supports staged nitrous, and flat shift.
Feel free to disagree with anything I've written. But don't simply tell me I'm wrong, back up what you're saying with some screenshots and or technical information that outlines the abilities of the diablo tuner. I spent a fair amount of time on Diablo's website and came away less than impressed. The abilities of the Diablo were only briefly outlined and there weren't any screenshots of what the interface actually looks like up close.
