I understand, I just want this to be a relatively civil thread. Lots of people get wrapped around the axle over dyno info (not saying this is the case, just stating), and not a lot of people have had good data to look at to try and understand. Everyone has a different perspective.

Also, I wouldn't expect the stock box to necessarily gain hp with the lid removed due to filter/elbow restriction, but I wouldn't be surprised if low-RPM torque was reduced by removing the lid. Removing the lid would effectively shorten the intake tract.
My measurement comparison between the two is strictly speaking from manifold to MAF housing. My box is modified Newmission, snorkel delete, etc., and has been tested in multiple configurations, to include directing air at the plenum to remove vaccum (to simulate driving at speed). The lid-off information is actually relayed from Red's dyno info. I can't honestly remember if I tested that way or not, though I'm pretty sure I did. I would have to get all of the original files to see as we are nearing or over 30 pulls now.
