extreme street losing some punch ?

hey guys ! its the rookie again asking more questions so i can learn something hopefully . i've been running the extreme street from eric for about 2 or 3 months now and love it ... (thanx eric ) . i was just wondering if anyone else has noticed a slight loss in power when changing tunes ? i recently had to tow my 7.5 ton dump trailer and put it on the canned tow tune then the next day loaded extreme street again and it doesnt seem to have the same punch as it did when i first loaded it . maybe i've just gotten use to it or something but figured i'd ask just in case there is a common issue and you guys know how to fix it. also with the sct tuner i have what does locking the tc do and whats the purpose ? thanx in advance !

usually its the opposite because when you reload the tranny shifts harder since it is relearning so it seems like it is stronger when you swap tunes. Atleast thats how I felt when I changed to a tow tune and back to Xstreet.
