Ecu upgrade
I have a 2011 bmw 335is...I bought it 6 months ago. I currently have 41k miles on it. It's a daily driver and I drive about 500 miles a week with it. I want to upgrade the Ecu for upgraded performance , but I've heard it's can wear down the engine , and that wouldn't be a good idea for me since i drive so much. Can anyone offer me any advice or any info on what they know about Ecu upgrades?
