The best way to interpret dyno data is by comparison, not by absolute numbers. Thus, my takeaway is that the mods added a much more believable 
22hp. 
As Radium pointed out, the absolute values of 250hp and 271hp are questionable and simply adding 18% to the measured value of 271hp is even more questionable.
