I just got my DME updated at the dealership, and my exhaust got quieter. Yesterday I had my secondary cats cut off and I love the way it sounds, now it sounds like crap.

I do I fix this, or get rid of this update?

Also idle isn't as smooth and my sputter has returned.

I am providing pictures of my update to see what software version I have and if you guys can tell me anything about it.

ISTA/P version - 50.4.002

Integration level - E89X-13-07-503
