all i can say is make dam sure if you go vacc mod it is set up right.. once its in you gotta pull the dam thing to adjust it.. i do miss the ablity to adjust my line pressure as mine shifts less firm then i wanted but being my was setup up my FLT im guessing where it is is probally where it should be
the verdict: if set up right(either way) theres no difference
