I have been driving in all modes and notice the difficulty in all of them.
The problem with turning off the traction control completely is that I think the car defaults to comfort when you hold down the button to turn off all traction control. The car feels much slower in this mode and the sport symbol disappears from the dash when traction is completely disengaged. Quote:

However the reason is to give you more precise control over the throttle as the assumption is that if you’re in that mode you’re driving close to 10/10ths, probably on a track, and need to make very fine, small adjustments to the throttle. Since sport mode throttle is boosted in the early part of the pedal’s travel, you get more gas per inch (but early in the pedal, not evenly throughout) than in comfort/linear. So the linear mode is less “twitchy” and allows for better and more predictable control when small adjustments are needed regardless of where you are in the pedal. I think there’s a mode with only some of the nannies partially disabled (DSC off maybe?) that still uses the sport map, if that’s what you prefer. I think I have a pic of the various modes around somewhere I’ll see if I can dig up for you. Oh, just had a thought. You might be experiencing the infamous BMW clutch delay valve (CDV). Some of the F30 manual drivers would have to chime in on how aggressive it is in the F30, but I know with previous-gen 3-series a lot of owners would remove/modify it. Do a little googling to see what I’m referring to. |

As others noted, the handling is a factor of the X-drive suspension and also likely a pretty narrow tire/wheel setup and also probably mediocre tires on the 335. Unfortunately, it will take thousands to get the 335x to perform well at the auto-x.
Your 335x is also making around 290whp/300wtq which is likely more than what your Stage 2 2015 WRX was making, but the 335x has an extra 400lbs to contend with. Adding a JB4 or flash tune will add substantial power and will make the 335x much quicker and quite a bit faster on the topend than your old WRX. The 6MT likely doesn't feel as lively because you got the X drive. It deadens things a bit because there's so much traction. In order to turn off all nannies, you need to hold down the DSC button for more than 5 seconds. Then the traction and DSC indicators will light up telling you all nannies are off. Sure, you only get the more linear Comfort throttle setting, but everything else should feel more alive. I came from a 2012 WRX hatch with a Stage 1 tune, a serious quality suspension, and a great wheel/tire combo. My stock M235 6MT blows that thing out of the water. The WRX was a fun car, but it's nothing compared to the M235.

My 340 is pretty quiet. It has a few rattles in the interior (one of which is somewhere in the headliner near the sunroof which makes me want to rip out the headliner). Im just afraid that my car will have more rattles after I get it back from being repaired ....

My rattling is mainly in the rear door and in the seat. I don't believe anyone would have taken anything apart there. I on the other hand have ripped out a bunch of the dash and center stack already and none of that rattles.
The bigger problem though is the wind noise. It's like I might as well just remove the windows because they don't do shit. I am always pressing the window switches up hoping they will move and bring some quiet. It's like they're always open a crack .. but they aren't. |

Which would you say is easiest to revert back to stock with minimum trace?

Its been proven already and a couple people can probably vouch for it. It literally takes 40-60 seconds to revert back to stock ( you can literally do it outside the dealer) and then reflash after you are done.

To my understanding though the dealer can see how many times the ECU has been flashed. If it's higher than 0 it gets flagged.

Also have you physically checked to make sure all windows are actually closed tight? Sometimes the switch can lose it’s position and think the window is closed but it’s not. There’s a way to reset it, I think you hold the switch for some number of seconds - if you search a little you should find some posts describing how to do it. I’d sit by each window with the car stationary and close the window, listen for that characteristic smooshing and slowing sound as the window squishes tightly into the top seal. Another possibility is that a door is misaligned or you have a bad seal, so if the above doesn’t help then I’d have a dealer check it out. IIRC some people complaining of wind noise have said new door seals helped. |

I do not deal with the dealer ... they don't know shit and will only screw things up and try to upsell me on unneeded work. I would never take a car in and say "figure this out and mess with it randomly" without first being able to say "do exactly this (for free, under warranty ... which I haven't completely voided .. yet) and here's why".
There's nothing wrong with my particular car. The problem is the glass is thin and cheap and there's no thickness or sound insulation in the door panel. These just aren't the tanks they were pre 2008. Cheaper materials used, maybe one step above hyundai build quality. |

In no way, shape, or form does it sound like a window is open when all windows are closed. YMMV. |

I also find the wind noise to be quite bad in the F30. Again, my opinion. |

flash is sooo much better than piggy back. MHD will full release soon. I have the beta. flashing with a phone is amazing and the first flash takes 20minutes, the rest take 5 mins im not sure why someone here said the flashes take a long time lol. I'd say MHD will be equivalent to BM3 by full release.

BM3 unlocks in 4 minutes and flashes in 1 min 20 secs first then 40 seconds afterwards. So yes, MHD takes a long time. |

After all my homework I was convinced the JB4 was the safest and leaves the least trace, but it was the least functional and cost the most.
Is this conclusion not accurate? |

This eLSD has me intrigued. Can people confirm on the LCI that you have to turn everything on to enable it? I've had everything off and the car is just a handful with the open diff.
