I think what surprised me is the rpms at which the peaks occurred.

Those gains, especially the torque, is really surprising. I'm assuming
that the air filter is the paper type since the R/T is stock. I ran
with the filter out quite a few times last year on the track and it
didn't improve my ETs but it raise my mph but by less than 1 mph.
I noticed that, with the filter out, both peak rpms dropped ...
don't know what to make of this yet.
Thanks for the report.
