Hey folks,

Driving a 2018 M240i Xdrive over here, and I am looking to get a bit more power out of it. I have read a bit about different tunes available, but I was curious to get some opinions on the best invisible tune.

What are my options for easy install/unlikely to break the car/easy removal at end of lease/if stuff breaks. I know several companies offer warranties, but not sure how these apply to leased vehicles?

Also wondering if you think it's worth running by the dealership first, or if these things are pretty problem free.

Thoughts?
