That's great. Yet, as with any mod that messes with stock engine tuning, the warranty will be void if the dealer finds it.
For most yes, but companies such as Dinan are recognized by BMW, and their tunes won't void the warranty. I do agree 100% with the rest of your post. I currently own a 2011 E90 335 M Sport, but just ordered the F30 328 M Sport. I know I am going to miss the N55 a ton. My reasons for the switch have more to do with being practical than anything else as I have my first child on the way and need to consider the lower car payment, lower insurance, and lower fuel costs. But some day I will go back to the 335. Or the M3. Or the M5. Or the M6.
