i wasnt sure if the mp-8 did much either, so i tried a few things

edge juice timing and setting 1; normal acceleration i turned the mp8 from stock all the way up while accelerating and i felt some pull.

edge juice timing and setting 5; same acceleration and turned mp8 up again and i felt more pull.

it just jacks up the rail pressure to around 29k psi, and i think without another programmer or larger injector nozzles it just helps to atomize fuel better.

but i def. notice a difference with the mp8 when the edge is on vs. off

 

My overhead never told me it was in regen, last flash about 5 months ago. The only way I knew (before all that stuff fell off) is from the Edge. It will tell you it's in regen until complete.
