Few questions (yes, I searched first)

[sonicboost14]

I've searched but either I worded it wrong or it was too vague.

1) Trifecta tune
Can you reverse or return ECU back to stock? On the canned tune: can you "pre-select" mods like exhaust, cat removal, bov, etc without having them installed yet?

2) Second cat
Can you remove it without throwing a code? Is there a downstream O2 sensor?

I'm not going apesh*t on mods, just making it more drivable. I'm going to focus more on suspension and handling, but those don't require programing.

1) Yes, if you have the cable and software you can flash back and forth from the Trifecta tune and stock tune. A canned tune is just that, a canned tune, if you go with the full tune you can list your mods and they will tailor it to your mods as well as give you tune updates. You'll have to request ECP to be tuned in when ordering to run a BOV or the car will not run correctly.

2) You can remove the second cat without throwing a code, there is not a third O2 sensor. If you get the Trifecta tune and have the cable you can remove the down pipe (with cat) and install a castles down pipe and use Trifecta's tuning software to turn off the CEL for the removed cat.

All of this has been covered a few times over....
