well i just got a pcm from mpracing and was wondering how long does it take for it to iron everything out and learn everything, ive put roughly 75 miles on it and it seems its just getting to the point to where the tranny is not sluggish as in when i first installed the pcm, thanks for everything

and yes i searched, and no i do not major in english :)

usually a couple hundred miles. Just drive it around for a bit for the pressure in those lines to build up.Dont drive it too hard

and ive heard not to drive to hard, which i havent really (except for maybe this one time.....) what is the reasoning behind this?

The thought is that the computer doesn't know the particulars of your engine and that the possibility of damage occurring due to a bad mixture is possible. Just drive it normal and worry about it later. It'll take affect soon enough.
