Hello everyone, My name is Jordan and this is my first time posting on the forums. So if im posting in the wrong area please let me know! Well for starter i have a 01 audi tt quattro. I have a fmic on it. Hallman pro mbc. Full 3" turbo back exhaust. K&N Intake. I also have 440 cc injectors but i have not put them on yet. Which brings me to my question. Im looking for a air/fuel converter that will piggyback into my ecu and let me tune it. I see apexi and i know there good. Anyone have any suggestions. New or used? Best bang for buck? Thanks all!!

 

piggy backs like that suck. look into getting your ecu chipped. unitronic, revo tecknik, apr are places i would look at. not sure if apr has 440cc ecu file but unitronic and revo may.

 

Well how much does a ecu chip cost? and can i just plug it right in or how does it work? And i was told that a piggy back to the ecu allows you to fine tune it and get it just right.
