so i've been looking around the site and been researching...for my turbo i think I may go with a garret t3...(not really sure on the numbers i know its 60trim dont know the ar)..although i hear that the 57 trim with .48ar is more efficeient....and for the ECU stuff i was told for an auto i should use the piggy back ecus instead of hondata? whats the input? and what are piggy back ecus...and what are some popular ones? i am looking to also throw in a tranny cooler as well and my goals are around 250 for a bone stock ls
