So i bought a 05 wrx a few months back and it came with the ap but was for a 04. Already married to car with stage 2. If i go back to stock is that a 04 stock or 05 stock? i did this to unmarry it and got a.check engine but cant check it.
Can i get a base 05 map to put on the ap to revert it to stock? if so where can i get it or does someone have it.
