What's new in fuel inj.?

   Hate to ask a question that is probably obvious to many here, but I've been out of the scene for about 5 yrs or so.  Anyway what I was wondering is what improvements/ new products are available in fuel injection?  When I jumped ship 5 yrs back it was HP inc for throttle bodies,  SE race tuners had usurped the power commander and though there were some initial "closed loop" FI systems they were pretty new and primitive and you couldn't get anything for a big inch motor. I can't remember who was making the units which were available at the time but it was still early days for closed loop then.  I think I remember hearing S&S was coming out with something but I was out of the perf biz before they did.
  Mainly this closed loop system is what interests me.  I have a 124" softail in about the 140/140 neighbourhood but for whatever reason the tuning keeps slipping on it.  I had to get it retuned after 2 seasons to get my numbers back up to 140 since they had dropped 7 and 10 respectively.  I can't figure why but it does.   A closed loop system that is constantly retuning would be ideal in keeping on top of it in terms of optimal tune if the product has come that far.

   So what can y'all tell me?

Thx
