It does reduce the torque dip/crater therefore smoothing out the powerband.
How else would you describe it?
I don't think anyone is talking about mashing the gas pedal and expecting some kind of miracle. I read it as not as much power loss when doing regular driving.

I you down shift when decelerating you don't fall in the torque dip when accelerating next. If you are driving above the torque dip and not expecting acceleration just by mashing the gas pedal, torque dip is not a big problem. And, yes, somebody posted about avoiding down shift (see above). Apparently, some expect that miracle.
One thing that needs to be said here that many people with the header and tune don't want to say is that this car is still slow and will stay slow with any mod short of FI.
The OP is asking "will I feel it"? And my answer is "no". Header and tune will not help making this car fast. Is there a 0-60 improvement posted that I missed? But modifying the car is fun as a hobby. I can't argue with that.
