New to the B58 platform. Traded in my MK7 Golf R for a '17 M240i with only 7k miles. Super stoked to finally own a BMW. Super impressed with the stock performance on this beast! I was debating just a down pipe and JB4 would be enough but I much rather have an actual ECU/TCU tune. Only thing holding me back is my CPO warranty that's good until 7/2022. Have any of you tuned folks had any luck with warranty work? Even though the dealership told me they were mod and tune friendly, I still don't believe them
