A lot of money for what's a TBI system. You can get a Holley 670 system for a lot less money, it doesn't look like a Holley carb, however.
So I guess if you've got the bucks and the need for injection that looks like a carburetor then you have your answer.
How much more power than what? And no, injection systems are not self tuning, the O2 sensor gives it a little capability but it really isn't there for self tuning, it's function is to trim a very close to correct mixture to correct.
