Best Tunning Chip for 2018 M4

[eflaherty9]

Hi All,

I have a 2018 M4 Manual transmission (425 HP) and now that the car is out of warranty I am looking for the best tunning chip to increase power. Please let me know your thoughts.

Thanks,

Ed

This is hard to answer, as it's like your favorite flavor of ice cream. There are many approaches, many tuners, and many goals.
I make custom tunes for these, with the goals on factory-smooth driving behavior, keeping the engine and crank hub safe, and reducing a lot of rev hang in the manual transmission.

For what it's worth, there is no "tuning chip" it's all done via a software flash.
