You'll likely be ok with those mods but you are pushing the limits of the fuel system. One flake out of the fuel pump under extreme load could cause a major knock event that could take out a piston or hit the piston so hard that it hammers the rod right through the oil film of the rod bearing and then you spin a bearing.
If hearing this makes you nervous, then tuning and modding may not be for you. Sure, lots of us run way more power than stock, but plenty of turbo BMW motors have died early lives stock, lightly modded, heavily modded, etc. There are risks to modding and driving hard. Don't trust anyone that says it will be fine assuming your tune is perfect unless they're backing that up with a warranty. The burden of proof is on you. They have many outs in the event of a failure. BMW will very likely deny warranty coverage too if something fails. You are pushing the motor outside its design limits and safeguard thresholds. If you do tune, definitely run the highest octane you can and preferably stick to a 91 octane tune even if you're running 93 or higher. Watch your oil levels and change it regularly. I've done used oil analysis three times now and BMW 0w30 is done by about 5000 miles before it starts falling out of it's viscosity range. |

This is why I personally only recommend going as far as Dinan goes, because we know the factory warranty would cover it, so it's within the general limits of the engine.

I'm curious to see what kind of N55 flash tunes they come up with. They told me they should be out by the end of this year or early next year, so I'll probably go with that. People like to take different levels of risk. For me, the peace of mind that comes with a warranty is important!

Err... no, the factory warranty doesn't cover Dinan mods. Dinan provides a factory equaling warranty that covers claims when the factory won't. Their piggy back offerings are conservative, and I've not heard of any claims to Dinan for catastrophic failures, but my understanding is that if your car isn't 100% BMW + Dinan, their warranty and BMWs is voided. If you go with a third party FMIC with your Dinan setup, because their FMIC sucks, you're out of luck. Fit the Dinan resonator delete yourself, you may have issues making a claim etc.

BootMod3 Stage2 N55 EWG 93 octane is a smooth powerful tune and the included automatic transmission tune is tremendous. I considered a custom tune ($500+) but people I respect advised against it. The OTS tune is powerful and safe. I was told that it would only be worth spending $ on a custom tune if I was installing more exotic fueling and/or a larger turbocharger. Good luck with your mods! |

Most dealers will look the other way if the part says Dinan. Only some will look the other way if it doesn't... |

It’s either 1 or 6. Clearly from the photos it’s one end.
