Hondata

i need to get my car tuned and i have to drive there in VAC. the hondata i bought is used so the specs are off. it was tuned for 550s with a fully built ls/vtec setup. i have a LS motor running with 440s. any suggestions?

previous owner got it tuned and setup to his specs. my question is, if i buy it, can my tuner re-do all the specs to my liking or am i stuck with the pevious owner's specs?

also, can someone explain to me exactly was datalogging is? i read it on her but i don't get it. i won't be tuning anything ...
