TC improve trap MPH

on my 01 GT auto.. if I get an after market torqe converter can it help my trap MPH..

Probably not. Trap speed is a measure of power and with a higher-stall TC you're not putting anything more to the ground.

You might gain a smidge if you could find a TC with a strong-enough lock-up clutch that could be engaged during the run to reduce slip-related losses.
