i have a 98 mystique ls 5 spd v-6 and i notice that at 4000 rpm my car gets a major boost...is that a normal thing in these cars and if it isnt what could it be?

yup, those are the secondaries. the duratec V6 have primary and secondary ports. The secondaries stay closed until about 3800 rpm to make low end tq and then open up.
Heres a pic to better illustrate what were talking about:
