Guess I should have said that too.... SD is huge with the domestic croud.

Also, like dumdum said, I would wager it's even more picky about mods then a MAF based tune on the WRX/STI. If you change your cat back I'd tell you to make sure to re-tune it.

Different brand high flow filter? Re-tune to be safe...

You get the point.

I know on the Mustang you could change hardly anything without going back in and making changes, especially if it effected vacuum at all.
