Yeah, they both are still in the programming as best I can determine.

One puzzle I'm still trying to get an answer for is that EFILive shows a max value for engine torque of 640 ft.lbs. I'm sure my engine is producing significantly more than that at the crank, so I'm not sure what, if anything, the PCM does at that point when that value is exceeded. The PCM uses two methods to try to reduce power when it wants to. One is via reducing the timing advance, and the other via fuel cut off. If you've ever had a situation where you get REDUCED ENGINE POWER, you will likely have noticed that your gas pedal is effectively useless.

And I did not disengage traction control while driving the car doing these runs, but I didn't notice the engine losing power if traction control kicked in. Actually a couple of times it did feel like the rear tires broke loose under boost, though....
