that is runs like crap on 91, but with 93 (yeah I know that's not what it should run on) it's a animal (relative to what I have tested). With 100 octane in the tank and the 100 octane program, it seems like it would pull forever! When I run 91, my timing gets pulled pretty hard around 3500rpms. If you were running 91 octane, that might be why the APR seems so weak.

Comparatively the MTM and ABT seemed weak when I tested MTM (older version), APR, and ABT on 93 (A-Box). ABT was the smoother of the three. MTM was just ok everywhere but never excelled at any one thing. The APR seemed to have the most torque down low and pulled harder up top. The APR could have seemed like this because it's not as smooth as the other two. I can't say.

These are just my findings...
