Completely stock. It requires 95 RON, but I only run 98 RON. I was also surprised by how high it was (even confirmed the number didn't include atmospheric pressure), especially since it gets increased by all the chips / mods etc.

Yea, I would be very nervous adding boost with an aftermarket device to where it could be upwards of of 23 PSI+ without some serious visual knock detection, high octane fuel and perfect mapping. Throw hot climate in there and this all seems like a recipe for disaster. |

There is no free lunch out there, 2.0 litre engine (non-race car internal build), with pretty high compression, smaller turbo to bring boost on early, running 95-98 octane in high ambient temperatures and high boost (20 psi), fairly lean for good gas mileage, has to be on the brink for long term reliability at 255 BHP and 295 TQ. One thing that was interesting is that the stock wheel HP was 240 on a supposedly low reading dyno, means the stock real BHP is more than the advertised 255, no? |

Your thinking is exactly like mine... basically lots of questions and I honestly don't have the answer. I'll get a new box back, I'll put it in and see if there is a difference. I had the box since July and it never really felt like it worked properly, so I'm leaning towards fault in the box / map. But yea; I'll know more when I get another one, and a higher model that allows remote map updates etc. I can't complain about the service from TDI and they're adamant it should perform better.
I was surprised about the stock power readings at the wheels. But having had similar cars (2L turbo etc) it feels (butt dyno) like the readings are about right to be honest... and BMW have under rated the power. It's worth noting that I have the launch edition with a build date of 11/2018 - seems like the earlier models might have been a bit different. |

What do you mean about the early build date, are they rumored to be higher rated from factory than recent builds? |

Not driven the JDM or even that model STi, interested to see what you think. Now the fires have died down and the temperature isn't horrific, I'll put the new chip in and run it again in a couple of weeks (after it arrives). |

Here in Brasil people are tuning their g20s at a place called armada performance and others as well, quoting gains of about 350 hp and 50 nm torque for the 330i M sport.
Is there anyone one now that we can truly tune a 20?

I’ve seen companies in Russia and Europe too that have been tuning G20 330is to 300+hp on stage 1 (only software; no hardware mods). I wish some of those people would join this forum and give us their insights.

Just caught up reading all the responses on this thread, just want to clear up some questions and concerns:
The B46D is in all 330’s in NA, including my very own after checking the VIN. The quality of the B46D is the same as the B58, same compression ratio, same cylinder bore diameter, etc. The only difference is that it has SULEV parts installed on it in order to meet emissions requirements. The upgraded B48TU is used for stock 300+hp vehicles produced by BMW. This upgraded engine is made to push 300hp even while running lower than 91/93 octane. It is made so that while running low octane, the engine will still be able to make the same power. We can see this because of the lower compression ratio which is found on the engine. It has very little to do with reliability of engine, it has everything to do with gas quality, however. |

So the G20 330i, no matter where in the world has the B48D, which BMW didn't seem comfortable tuning to 300 HP or they would have used the same B48D in BMW vehicles producing 300HP instead of up-rating it to the B48TU, is that correct? As you say, this is probably related to the fact that they have to account that certain regions don't have access to 95+ RON so to achieve that 300 HP stock on potentially lower octane fuels they had to dial down the compression to avoid knock / det - makes sense. So again, tuning the B48D to 300HP is probably OK if you have access to 98+ RON fuel, don't live in a very hot climate and don't track your car. |

Also, don't understand the logic here. B58 is running 382 HP and 369 TQ, so 2 litres / 3 litres or 4 cyl / 6 cyl X 382 and 369 = 255 HP and 246 TQ. HP is almost bang-on and we are actually quite lucky to have 295 TQ based on our engine being down 1 litre and 2 cylinders on the B58. This engine is being pushed pretty hard right from factory so not sure how much room it has in a hot climate running 95 RON / 91 API octane, my guess is not much room at all safely.
