Any catastrophic failures with tuning?
I'm thinking of adding the following mods:
Akrapovic catted downpipe VRSF charge pipe Wagner intercooler BM3 stage 2 tune I don't think I'm pushing the car to its limits, but I am aware of the risks associated with aftermarket tuning. But I'd like to hear from those who've had MAJOR breakdowns (blown engine, etc.) as a result of a similar setup. Am I being too much of a p**sy? LOL Any feedback would be appreciated! |

Unknown if the failure was related to tune or it was just a weak engine. |

98% will depend on who tunes your car. Mechanically, people have taken the stock n55 block to 600-700whp without issues.
But strongest engine in the world can't protect itself from crap tune. |

Apparently Dinan's n55 flash tune will be out soon, but has anyone tried the following Carbahn tune by Steve Dinan:
https://carbahnautoworks.com/product...56lb-ft-fw-tq/ I think the $500 factory matching warranty would be worth the money if the tune is decent. |

You mean get super knocking like mine?
If you get this at the track even if the engine doesn't die the piston is likely to be cracked either way. But keep in mind that super knocking and knocking is not the same. Next time I go back to my mechanic I will try to capture how bad the piston was. They took it out but I forgot to take a picture last time. To that point, I don't recall anyone that saw my logs for that day indicated any issues with knocking or octane. IAT was an issue though. Logging will help with regular knocking but not super knocking. Don't use BMW supplied oil. This was one of variables that changed from my usual track days and likely contributed to oil intrusion causing the hot spot on the side of the piston. If you run really sticky tires stay out of lower half of RPM range. LSPI is another major variable that leads to super knocking. |

If you want to feel a bit better about the longevity of these engines tuned, visit a Subaru forum. I'm speaking from years of experience with a tuned 06 STI where I saw "blown ringland" threads pop up weekly'ish. Get a custom tune if you're overly concerned.

Track Rat's can expect issues, his OTS mods won't be part of that.

How would a custom tune be better? Are you saying I should tell the tuner to keep it less aggressive?

The tune is made for your car with your mods running the gas you have in your area. OTS tunes are generic to all vehicles whereas custom tunes are specific to your vehicle only. You log wide open pulls and send to your tuner. He makes adjustments depending on what he sees and sends them back to you. Lather, rinse and repeat.

Is there a tune specifically for bigger turbos? I've asked several times and they always say that one is in the works but don't know when it'll be out. There's so many variables. No two people have the exact same mods. I'll bet that no one on this forum has the same specific set up that I do. Probably not the same as you either if you're running anything other than stock. Custom tunes don't have to be aggressive or they can be very aggressive, it all depends on what you're looking for. |

a custom dyno tune would be the safest kind of tune depending on your tuner. Most people opt for highest hp as possible dyno tune so they can brag, but more seasoned people know go reliability, drivability and then power in the tune. like i said in my original post you need to have a reliable well informed tuner, that will make or break the engine. |

But it's usually not. No one wastes money on a custom tune that they can get with an OTS tune unless they are doing non-standard mods, or want to wring the most power out of the car. I think we can agree to disagree here, as I agree that a custom tune can be just as safe as an OTS tune (or safer), it's just that it's usually not. The whole reason the companies that make OTS tunes are in business is because of how safe their tunes usually are. |
