Yeah, after about 25 miles I got the Increased Emissions warning. Everyone does. It doesn't affect the performance but it's annoying. I have enough warning lights going off in my Jeep, don't need it in the M3 too, haha. The tune will eliminate that though along with providing some other performance benefits.
I'd say go for it, just know what you're in for and set aside some money for a Stage II tune at some point.
