It seems like a pretty affordable mod especially if you plan on doing a lot of upgrading but is really as good as it is hiped up to be. I'm thinking about getting one for my turbo sohc civic.

 

I've got one but haven't really gotten into the nuts & bolts of it as much as I would like to as of yet.

It seems like an excellent setup and will only get better with time. Right now there aren't a whole lot of people using it, and as such you are mostly on your own, tuning wise.

I wouldn't recommend it for the amateur tuner... it is a lot more complex than a VAFC or Hondata setup. But there are a whole lot of people out there that can tune it for you.

 

The revmatching and boost control functions look pretty promising... and tinkering with the spark/fuel curves does seem too difficult (of course, knowing how is the hard part). I plan on getting one eventually myself.
