im pretty new to the auto-x thing but last run i did. i guy that does this for years. recommended to run 40 front 44 rear. (which doesnt make sense to me) but i followed his advice and my time dropped by 6 secound. all that crappy understerr and pushing was gone. the tail wasnt too loose but it was loose enough to get the front end in the direction i needed it in and at a much faster speed. i droped from 53 sec to 47 secs.
go see for yourself.
