I really appreciate you doing this.  Fun to see the differences.

How about this bad boy?  This is my final what if. :)

No.. no final what ifs required.... I like looking at the data myself.... it's fun.

I have always hoped that one of the cam suppliers would look at my mock pulls and cam profile specs and chime in to say that my Performance Trends data is ca-ca!.... but so far no one has "officially" challenged the data, and offered certified dyno test data... other than personal experiences and "butt dyno" feedback.

I'll plug in the specs tonight and update the sheet.
