I don't know what makes you think press test numbers are the be all end all. So what? Ok, you take a car on a strip. So? The press cars aren't ever prepped for a strip and they likely aren't even testing on a strip.

BMW changes the files to keep the CEL from coming on from repeated laps as stated along with other things. I mean I don't have a whole breakdown for you as I did not develop the software but obviously there are changes to parameters that affect things other than acceleration.

You seriously think there is just one map? We had reports that BMW was testing the cars with over 700 horsepower. Doubt it? What do you think they do? Just develop one file and that is the chosen one? "

I know it's being stated, but I'm saying I simply don't believe it. I think this is a story that was told by a few and got passed around as fact. Not trying to say you did that, but just in general that seems to be what everyone always says. Also, the people who had their car "press-tuned" by guys who supposedly were able to even do that mysteriously never get their cars dyno'd or run them at the strip. Always seemed funny to me. Like many say, I believe that the "press tune" was a leak of the comp package tune. That would make sense to me.

Its not really a big deal, I just like to stick to known facts. So far, I've never seen a BMW that didn't perform as well or better than BMW or the journalists said it would. Now Ferrari on the other hand.... "

Thanks mate. Trap speed was 129mph (207km/h).

Ill take a full photo of the time slip and update the thread so you can see the whole slip. "

" Congrats on this man! I know you've worked hard to get this kit out!

Any plans on doing a ceramic coating option?

You are running the 700hp turbo now? Or the 800? Any plans on swapping those 4 turbos around on the test car to show difference in spool/power on the different options? Just curious, being a top mount I know it's easier to do than us bottom mounters lol. "

@lulz_m3 Thanks for the advice, I got everything sorted out. Just needed to disable the codes.
FYI I was being sarcastic. "

Further thought makes me wonder if the value COBB is giving you is the DME calculated theoretical torque, i.e. without internal engine friction and parasitic heat losses. That would be enough to explain the remaining "bonus" power in the data.
Your driveline loss calculation is on par with mine. I calculated it at 15% driveline loss after the crank before the wheels. Also the DCT has no torque converter like the AT do if that matters.
@Josh@Cobb can you give us some insite of how accurate this paramter is in calculating torque and how it is coming it with its numbers ? "

I know the person who originally wrote the tool. There are files for downpipes / bigger turbos / etc. There are full editable definitions available for all F cars if your wallet is deep.

It will be more common as more tuners purchase it. And the truth will be revealed soon.
Show me a dyno tuned F80 M3. "

The Competition Package stuff should be well known. It should also be well known that many Mercedes tuners used the factory AMG P31 file as a standard C63 tune. This happens with multiple companies not just BMW.

Regarding the flash baseline we saw it was a little low not that all dynojets read the same. The tuned run wasn't even higher than the majority of baseline runs we have seen. So, what's really up?

The fact is nobody has control of these ECU's. I don't care if you can get some factory file to write. That isn't tuning. "

As stated it is not just about power. Additionally, press files exist for multiple manufacturers.
