MX-3.com

hey there all. i am wondering if any one out there can help me. i am looking too put a chip in the ecu but need some advice on where to get one, which are best, accurate performance details. any help would really be apreciated. thanks in advance

there are no really chps for the mx-3
i would just piggy back the ecu

can you explain to me what piggy back the ecu is. how hard it is and how good it is
