Pretty sure, check the VIN, and to my knowledge from the forums the B48 didn't make it into the F30s in the states for some reason. Found that out after purchase, not a biggy, but considering the change took place in 2015 I was surprised.
Cars not too quick but at least you can hear the turbo in the mountain roads in second gear. 😂 In all seriousness power is alright I just want those 20/30 extra ponies. If only bmw would offer a small tune that just bumps up the pressure from that tiny turbo lol. Also unrelated, was checking if there is anything I wanted to code with bc but unfortunately no folding mirrors here, and when the car is in sport and I throw it to M it says S1 not M1, unless I start shifting. Not sure if that means it has the sports transmission enabled already, if so I don't see anything to code other than windows going up key fob. |

BMW offers M Performance sound and power kit for 335i and 340i and even for 320d but not for 320i or 328i for some reason. Maybe they don't trust N20 can handle additional power? S1 in cluster doesn't automatically mean you have SAT. Better way to check it is to put stick in S mode and car in Sport or Sport+ and accelerate hard. If you can feel slight jolt with gear changes, you got SAT. |

When I throw it to S trans it just gets a bit more aggressive. Did a pull and I do feel a small jolt in between gears, but I can also kind of feel that in Sport auto. Tried timing the 0-60 manually for the first time got 6.4 (pretty rough), will download an app to do better testing. Fully stock. |

I have a very similar car as yours, a 2018 320i xdrive N20 (pretty much the last batch of N20s I think). I have BM3 stage 1 for about 2k miles and without noticable issue, although I never logged or WOT, just normal daily driving to work or weekend errands. Btw I also have XHP stage 3 TCU tune.
Personally I wouldn't go anything more than a stage 1, and I am runing the 91oct map with 93oct gas. Fingers crossed. |

Hey, just to satisfy my curiosity, i just reflashed it for stock stage 1 91Oct vs the 93 i had, i still kept the same burble settings and everything else including the TBG(R%) 1st (30%), 2nd (20%), 3rd-6th (0%). Seems fine so far, can notice the drop in HP and TQ but it's not alot as i thought it would be...

I don't get it why you are guys worried. The headroom for this engine seems to be 450nm to the wheels which I would call stage 3.. Just look at the VW's 2.0 TSI pushing 300hp stock. |

One thing I've noticed is that it seems those with custom exhausts have less blown engines? I remember reading having a larger output after the cat was needed. |

After that FMIC helped the most as it pushed IAT from 60+ Celcius degrees to below 30 degree under the load (WOT). I would say that is crucial to keep it cool in the cylinders and their heads . My gains from the FMIC where around 30 whp and 80nm wtg just because the DME was pulling timing and the limiters were stopping the power to rise. Besides that the best fuel I can find, 0w40 oil and an oil flush every change - I am babying her and she is giving some love back . Plugs and coils when needed and I am keeping the train rollin'. Best regards |

i believe it is related more to the engine capability to handle more power and torque from remap |

Do you have upgraded turbo? Or it is stock?

I use 93oct gas on a 91oct tune because I want to leave more conservative margin. Tbh I cannot sense any difference in power between the 91ct and 93 oct tunes using my butt dyno lol. |

If a stock 320i is literally the same motor, minus pistons, as a 328i (N20) why would bringing up the boost to 328i numbers do damage to the motor? Obviously people who mod their cars rarely stop at a tune...but are there really blown motors on N20 that people brought up from a measly 8psi factory boost and didn't do other mods? Can the 320i actually only handle 8psi? If so what's the reason for that? |

I have a 2016 bmw 320i xdrive in mineral grey. It has about 47k miles on it and out of warranty now. I think I'm finally ready to jump on bm3 stage 1 but this thread is kind of scaring me. Is the N20 engine really not capable of handling the extra power? Would a jb+ or dinantronics piggy back be easier on the engine? I love my car and would hate for the engine to blow all for a few extra horsepower. Will I be fine with stage one if I just upgrade my charge pipe and boost pipe? Thanks guys
