Hello,
Haven't been back here in a while, but I've got one quick question that maybe you might be able to help me with. Does anyone know of a company online that offers upgrade ECU chips for a 1.8 Corolla 1zz-fe engine??? I've searched the forums but nothing was found, so if you could be kind enough to point me in the right direction, I'd highly appreciate it. Thanks.

Also, if so, how much of a hp / tq gain will this add to my car??
