...Also they have now purchased the BMW aus (if my memory serves me right) diagnostic, which means that the tuning is done in such a way, that no dealer (with the current equipment) at least can actually find out that this has been carried out..
ICEMAN is RIGHT everything can be seen by B(mw) IG BROTHER!

You can fool almost any other computer, why not the E60?

41hp/35Nm only by remapping??
Any graphs? Dyno run?
The midrange torque raise sounds very very good if true!

Homepage?
www.dmsautomotive.com but they never put anything up !
all i found "The BMW M5 our ECU Re-map gives increased power and smoother up shifts by mapping a softer cut in the rev limiter. Also mid range response is improved in both standard and sport modes. "
i suppose your best bet is to get someone to scan (i dont have a scanner)
the 3 page article from BMW CAR (UK) magazine...

I've been out in that very car, as DMS replaced their E60 535D M-Sport with the M5 & Rob (owner) has tweaked it & also altered the rev limits in the individual gears.
The car is awesome & having raced it a couple of times against my modified RS6, their was nothing to seperate both cars in acceleration & top speed with us matching like for like. My RS6 only has an extra 10BHP over the DMS modified M5, however with only 5 gears & the pair of turbos, they were matched perfectly. The M5 pulled a very slight lead up to 40MPH as 2 big turbos take a moment to spool up & the M5 has it's power available lower down the rev range, however this balance was addressed right up to our timing beamed 181MPH.

Not strictly true, as the RS6 having 2 big turbos, takes longer to hit peak torque as both turbos need to be spooling fully to get the big whack. I don't know the curve on an M5 (standard or tuned) but mine at peak was 562.3lbsft, but as said it kicks in later up the rev range. All normally aspirated cars have their peak torque lower down the rev range, as they are not waiting for turbo's to spool.
That said, diesel turbos are designed to kick in much earlier than petrol turbos, as they don't have the same overall rev-range. Diesels having a rev limit of between 4 & 5000 rpm & petrol turbos usually around 6750+. If i recall, the M5 has it's rev limiter closer to 8K rpm, being normally aspirated.
Of course i'm no mechanic so could be taking out of my arse.

Well DMS finally introduced their solution for the M5, and it has been reviewed in
BMW Car Magazine (along with the ACSchnitzer's Tension )
Anyways, DMS found that in P400 mode the car is limited to 250km/h and in P500 mode the limiter is set to 270km/h !!!! That was undocumented, and congrats to DMS for finding this out. Also they have now purchased the BMW aus (if my memory serves me right) diagnostic, which means that the tuning is done in such a way, that no dealer (with the current equipment) at least can actually find out that this has been carried out..
DMS have reset the P500 limiter (P400 is still at 250 afaik) to 370km/h so as not to interfere with the workings of the car.
The end result is 548bhp/555nm /345km/h ... The most notable gains being at around 3500rpm to 4500rpm where the car produces 80nm more than the original car...
They measured:
0-100km >>> 4.45seconds
0-160km >>> 9.32seconds
Thats it for today

Well, I had my 535D remapped by Upsolute
330 Hp (4.150 rpm) and 660 Nm torque (3.150 rpm)
That means 110 Nm more torque still... ( I took it to an independent Dyno rolling road to test)
And 290 Km/h as speed limitator was eliminated

Yep, because they were not looking for it. And maybe they have found it, but why should they tell you? Is there a problem caused by it? No. So, IF there is a problem that can be related to the remap, THEN they will tell you!
They CAN see it, if they WANT to!

OK, so you believe everything that's in the bloody magazine? The newspaper? The national enquirer?
You can trust me on this one, NO remap is stealth!

I cant think he'll risk it just by putting BS up
