not to sure if you can get a Power FC for $600-$800 ready to installed since the corolla needs a harness to run along with the stock ECU. the harness along normally goes for around the 400-600 mark its self unless you know a installer that will model the harness for you. tuning wise you will probably looking at 120 an hr and should take somewhere between 3-5 hrs depends on the tuner. its only really worth it if you have mods on your car e.g. full exhaust, headers (atleast ported), cai or short ram pod. thats what i think anyways.. im sure many on the forum can give you more advice.
