[QUOTE=alapoint;29912503]Im getting the Carbahn flash tune on the 14th. I went with Carbahn for a few reasons. The big thing is obviously its a well known BMW tune bybStebe Dinan, whos trusted, and not gonna cause issues with my engine(i passed on warranty for this). BMW wont have any issues with flashing it on or off in an event that needs to happen. Or, on a rare occasion there is a software update they can flash it back on. Although, most places like RK Tune, send you the tune and with a computer you can do this yourself. But my piece of mind is its done by the tech/mech that work on my car regularly and they understand my car and the work they did.
Also, If you notice, the tune doesnt increase torque very much at all. Its mostly horse power. Torque is what destroys a lot of these engines. Down low, if theres too much torque, it can actually spin the engine out of timing. Why lots of engines blew up. I had BM3 on a previous 550. Tons of power and versatily. I loved being able to change tunes and change my options on the tune in a matter of minutes. Few things about BM3 is theres a ton of torque way too low in some cases. You have to be mindful and use more rpm’s. The other issue i had, the tune actually writes over the cars codes so unless you check regularly on the app, no codes will pop up in the cars dash. If you take it anywhere for car issues and they plug your car in, they dont have access to the cars codes either. Not a big deal. You have to remove the tune and relock the dme each time. Again, 3 minutes each way. But…it can be a hastle if you forgot your obdii cord and [...] Also curious about this tune. Salesman was pushing me to do this tune when I was buying the car for big power under warranty. |

I love it. Havent dyno’d it yet but the car pulls like a train. The tune is designed to protect the car, so the torque is limited till after 3rd gear. But its fast. All top end. When i get it dyno’d ill let you know.

So no difference out of the gate ? I don’t mind mid to top end power but was hoping to get low end power from the tune.

If youre looking for a 0-60 machine, this isnt the tune. For me, id rather that because i dont race or do 0-60 standing starts. Id rather reliability and safe on the engine then a torque monster. I actually brought my car back to double check the tune cause it felt stock. It has crazy boost by gear reduction. Now, having said that, if youre looking for a 60-130 car this would be a great tune. The way is it pulls too end after a few gears is awesome. 4 gear is awesome cause it pulls like a bastard but 5th on the interstate will get you jail time faster then your eyes read the speedo. 160mph becomes ridiculously easy.

Alapoint, you said you brought it back because it felt stock. I'm concerned about this as I'm also thinking to go carbahn and there is no way to verify without a Dyno. What did the dealer say when you brought it in for that?
Totally agree with you, not having fault codes displayed on my dash is a deal breaker for me with bodmod3. That's why I'm leaning towards safe with carbahn. Do you know if the sport gauge numbers in the sport display gets updated with the new HP/TQ numbers? I was thinking this would be a good way to tell if it was done. |

The sport gauges are adjusted but only go to 640hp lol. They said its just a generic code and not really accurate. More of a gimic Dyno is for the 26th!! |

You gotta pay for the warranty and thats just a warranty that covers stuff voided by the tune if that makes sense. Any tune will ultimately void the warranty and theres no way to cover it up.

I would want to read the fine print very carefully on any third-party warranty That carbahn is giving you …probably full of all kinds of exclusions and loopholes for them to avoid pain, or to avoid paying in full. They have no interest in dropping money to fix motors.
If you want that much horsepower just go buy an M5 and keep it stock.

This tune is safe though and you can have 707hp for $30,000 less than a M5 and at the same time, a more rare car!! Difference is, the M5 is made for these speeds and corners, M550 is not. Its a bit of a couch strapped to a missle |

The one in the video is overly aggressively tuned, maxing out boost which will heat soak the cooling system (dyno queen as they say). His ots tune seems to be on par with the other tunes avail- between 680 and 710 hp, keeping in mind that car had some other light mods. |

Thank you for the info! Dyno Queen is funny ! His numbers are impressive but you are right you shouldn't have your Boost maxed out. The N63 is already a heatbox! Thanks for the info I'll do a little bit more research

Someone said "160 mph is ridiculously easy"
To me, hitting an indicated 163 (prob really 155) on the A92 during the Euro delivery of my e39 540/6 in May of 1997 felt ridiculously easy! Know what you mean, though!
