fuel rail pressure actual I assume the actual(as opposed to desired) pressure after the hpfp
mbt spark could be the calculated spark timing if the pcm is using the mbt tables. The truck may run in mbt(maximum brake torque) at light loads.
boarderline spark may be the calculated timing if the pcm is using the boarderline tables. This what it uses if it cant get to mbt spark timing due to lack of octane.
preignition, same as above but for when knock is detected.
Knk sensor timing adder almost sounds like Knock retard that we all talk about. Basically the real time spark adjustment
Injector pulsewidth is probably the time the injectors are open?
effect throttle area is probably a calculated flow are of the throttle body based on the angle. There are tables in the tune that tell the pcm the area.
