(Moved some comments down here as an answer.)
I think the problem you are going to have is that "seat of the pants" you are not going to be able to tell. It would be so subtle you wouldn't notice. The PCM will cause it to go in/out of lockup. The only way you'd be able to tell is by having a computer attached to your the car and see when the PCM gives the signal to the tranny for the lockup. One thing you have slightly wrong in your question is the lockup will disengage when the car "needs a little boost" ... it locks up to give better gas mileage.
When the TC locks up, it is very close to 1:1 already. When I say it's subtle, it's very subtle. I'm not sure of the programming, but would believe this is only going to happen in the final gear (if a 4 speed tranny, it will happen in 4th gear, etc). Also, your transmission will not catch up to the engine, your engine will slow down to your transmission, and then only by a couple hundred RPM at most. This is probably going to be your only indication that your TC has locked up.
