BMW M550 Carbahn dyno results
2020 m550 with Carbahn tune flashed at bmw. Has CTS intakes and Remus midpipe, both i highly recommend for the sound love love love it, great combo but probably like 10 horsepower combined and probably not in any spot that adds value lol.
Done at ACI Dynamix in Shelton, Ct. About 85 degrees and 85% humidity. Not ideal by a long shot. Aci runs a mustang dyno. These run lower numbers than the other types of dynos. But in the end, numbers are just for a rough idea of power since different dyno’s and fuckery with calibration make them a tad arbitrary . Ideally, draggy times are more accurate. Low was 576 tq and 572 hp to the wheels with high of 608tq and 602hp. So rough 590 avg to the wheels on a nasty hot day and on a mustang dyno. Carbahn quoted 580 to the wheels. Looks like they were not lying!!! So needless to say, i recommend this safe tune for anyone looking for crazy power gains. |

I was reading this on there website so you can opt to pay for a matching warranty ? Not a bad gig

I didnt get the warranty they offer. Feel like its a money grab and a toss up if theyd cover anything. If its normal wear and tesr thats one thing, but i bet if somethingbrole while hammering on it i bet they would call it racing and wouldnt cover shit. Who knows. But im gentle on my car and dont race.

The Remus mid pipe goes from the cats and clamps to the stock exhaust. Exhaust needed to be cut but its a fairly quick mod. And way cheaper than acle back muffler. Id post a sound clip but it wont let me post videos…. |

I should preface, I'm in m850i so the rotors might be bigger.
Re the tune- how's the pickup without downshifting, say from 3k? I noticed my motor isn't very responsive unless I manually shift and keep the revs high or floor it. This makes for not the most fun driving experience. I'm hoping the tune can help mid range response. Last edited by Dasky_spas; 07-14-2023 at 03:52 PM.. |

Stock pads so far also. The M Sport brakes have a lot of bite but i will say, i dont race and theres not repeated hard braking. You want race brake pads and rotors , it comes with noise and dust. Ive braked from160 down to 60 with no issues YET! But they are starting to squeal so life on them is running out. Ill probably upgrade pads to a Hawk street/race cross but thats it.

You mentioned it was flashed at bmw? As in a BMW dealership? Mind if I ask how much? I think the “chip” tune from carbahn alone is $1000, right? |

I got a veteran discount so it was $1350. I didnt get the warranty. To me, not worth it. Money grab in my mind. I wont beat my car so the chances are low it will bust my engine. I also switched to Motul 5W40 and 3000-5000 oil changes. With a tune, i think the 5w30 or 5w40 is a must. |

I wanna know how the xhp is on the downshifts are. I hate the stock downshifts. Such a half ass throttle blip. Its more of a clutch slip. I want a hard throttle blip that sounds awesome and matches revs. |
