How can I tell if my N63TU is tuned?

[BMWerkeUSA]

Hello,

I sold my 2012 650i about a year ago in the hope that I can get a 650i with an N63TU but the prices went through the roof. I ended up buying a 2014 550i with an N63TU. In sport+ mode, 550i feels faster than 650i. I know it has an additional horse power but either I don't remember how fast 650i was or 50HP makes more difference than I imagined or maybe this car is tuned. In any case, I am wondering how I can find out if my 550 has a stage 1 tune (Weistec or something else) without taking it to dyno? I do have ISTA/P as well as ISTA/D.

Thanks

Not only do you have more horsepower…the N63TU also has more torque…and torque is generally what is described as “what you feel”.

2012 650i (coupe?)

6 Series N63 V8 Engine:

• Horsepower @ RPM: 400 @ 5500
• (ft.lb) Torque @ RPM: 450 @ 1750

2014 550i sedan

5 series N63TU V8 Engine:

• Horsepower @ RPM: 445 @ 5,500
• (ft.lb) Torque @ RPM: 480 @ 1,750

Do you have the Sport Display feature in iDrive? I believe that when the engine is flashed/tuned…they can also update the sport display to reflect the HP & torque changes.

Thank you Qsilver7!
You not only answered my question but also showed me a cool feature of the car I did not know about. My display is identical to "before" and so I do not have a tune.
I just need to find out what tune Duff Ace got.
Thanks again for the quick reply!

If you click the link in my post above…it takes you directly to post #1 in his thread. If you look at the upper right (once you’ve clicked that link)…you will see another link that says THREAD: New sport display see the difference”. If you click that link, the whole thread will open and you can read down that discussion where he mentions what tune he got.

Yep, I had found it. Thanks!
