Halltech Killer Bee™ II C5 is it worth changing to?

I have a friend who has one of these systems for sale and I already have a k&n system on my car already and its a 418 ls3 that made 510rwhp unlocked ...I was wondering what yo guys think is it worth it or just keep what I have.... I am trying to get the best bang for the buck and the only thing I see that would be beneficial would be the 102mm inlet and maf sensor that is the ls7 style? any experiences would be appreciated.....

Are you running out of air? Map reading beginning of run to max power?

What is your Airflow & Frequency under Hi load?

Ls7 card style mafs will reads IATs differently. They always tell the PCM that the incoming air is hotter than it really is, when used with older PCMs.

This is quite true, and the difference when compared to the tables in an LS1 f-body PCM is not linear (granted, this isn't the same application here). HPTuners unlocked the table that deals with this in the f-body PCM, but I lost interest in trying to calibrate it.
