Any other differences are as likely due to transient factors (e.g., intake temps) as not.
Also, see if you can get those results in SAE, DIN and STD tend to skew high on NA cars.

There is definitely at max a 10whp difference in correction types.
I have my drf run files so I can so adjustments, but I've posted strictly DIN on other threads so I use it incase anyone cross references.
