UpRev question (what can I do)

[gaveup]

Basically, I have all the mods listed in my sig and already have an up rev tune from a tuner a decent ways away (and honestly I don't know if they are still open).

I have some CEL codes I would like to disable (Cat related) or possibly get the car flashed back to stock (for when I sell it). I've also considering going from test pipes to high flow cats.

From what I understand, the tune itself is in the cable. So in this situation where I can't contact the tuner (or let's say I moved to another state) what could I do to get this done. Would I have to spend $500 for uprev osiris just to do this? If so, it's probably a better idea to just throw the stock exhaust on and trade the car in.
