I guess it all comes down to porting technique.

was there any ECM tuning done to your combo at all, or is it simply the porting alone that is accounting for the difference?
I see that your PE mode A/F ratio is quite different between youir pulls, it would be interesting to see Locobobs A/F ratios as well.
