ecu?
 

i live in hawaii and want chip my 07 a4. what's the best and easiest way get it done? apr doesn't have any shops here.

GIAC (http://giacusa.com/dealermap/) and REVO (http://www.revotechnik.com/locateDea...=96801&dist=25) both have dealers in Hawaii. I would check them out. If you really want APR, you can send them your ECU and they'll flash it and send it back.
