Hey bob, I have carpet and mats from an 07 sedan. They're like new, the entire interior was. It yours for a hard copy of your first book plus shipping

And as for ECU, I agree on the Tec not being ideal for a subaru. After some research I decided on AEM. Their new ecu is quite impressive hardware and will run everything you need. Wayne is also a dealer, I case you didn't want to make a harness...but something tells me your not afraid of wiring.
