I received my download link for the Cobb Accesstuner (AT) software, so I finally removed my MPT 93PRX tune and installed the Cobb AccessPort (AP) and their hottest off-the-shelf (OTS) tune, Stage2 93. I still have the NGauge in the truck, so I can compare apples-to-apples data for the two tunes. I can say for SURE that the Cobb OTS tune outputs slightly more power than the MPT, but Cobb still lacks the trans tuning. The 10R80 transmission tuning is a priority project for them. The single PID to monitor for raw power is the Actual Load. Cobb runs slightly more boost which results in a consistently higher Load value achieved which equates to more output from the engine.
I didn't make any timed runs yet because the Learned OAR multiplier starts at +1.0 and you want it to adapt to -1.0 for the maximum ignition timing. I'll drive it for a while until the ECU adapts to the -1.0 value. I have hard data from the MPT tune run in Sport mode, so I'll run the Cobb tune in Sport mode as well. The MPT trans tuning helps the "feels-faster" aspect by having the gear/rpm correlation kept at the optimum even in Normal mode, so it feels like it's faster/quicker.
There are many more Cobb Custom Features that are included on their other Ford platforms that haven't matured into the Raptor AP/AT yet, but they're coming...
