IM NEW TO THIS... but u said that piggybacks are sh*t. why? i was looking at an uni-chip piggyback which i belive isnt ebay crap

Check what I posted again, ERIC HSU said that, not me. I was asking for this topic to be discussed and it has been to my satisfaction.
 
i'm really new to this stuff. i get the difference between piggy back system and a standalone. does an access port fall under one of those categories or is it something else
 
the accessport is a standalone, meaning it completely replaces the stock ECU's tune.

the piggybacks just alter signals sent to the stock ECU to change the tune.
