Next 35i modification...

[18BMWX5]

First, Happy Father's Day to everyone. I have a 2018 X5 35i X-Drive with the MPPK. I recently ditched the run flats for Continental DSW 06 tires which I like. Currently, it has around 25k with a year and a half left on the factory warranty. There are a few other things I would like to do in the future. I wanted to obtain opinions from the forum members. This is the family vehicle so I don't want to push the engine to the limit. In no order I would eventually like to do the MPE the M Brake Kit, and possibly a mid level Race Chip or some other stackable tune... Thanks in advance everyone!

Be careful with the tune. I ran the ChipExpress for about 5 years and loved the power. Aside from 2 tuning box failures resulting in new boxes, i started getting a lot of fault codes after 5 years i.e. both engine and transmission faults. After the dealer replaced many components (stuck valves, O2 sensors), it went back to normal. I miss the extra pull but it's not worth the repairs after.

(I used to run Race Chip in my previous car and had similar issues a little later in the life of the car.)
