E60 M5 v RS6 Plus

[Ernst]

I am new to this forum but would just like to add my bit.

Purchased an RS6 plus a couple of months ago and have just had AMD stage 1 remap.

Figures are 515 bhp and ~500 lbft torque.

Fantastic car.

By the way, here is a question for anyone:

I am after some winter rims/tyres and/or snow chains. Has anyone any experience with this? My local audi dealer doesn't seem to have much idea.

Hello W8PMC. When I got to QST we ran the car on the Maha rolling road and the figures were as per specification from Audi. We then repeated the runs with the MTM chip change and got 505BHP and 557lbft (755Nm). These figures were repeatable to within 0.5%. The Maha rolling road is housed in a purpose built building and there is full air flow management to make sure that the engine etc does not overheat. As a matter of interest, we compared a standard RS6+chip to my modified car and although the torque was not much difference at high revs, it was higher at lower revs. We believe that this is to do with the RS6+ having the sports exhaust as standard.

Now i'm even more confused. I can go with the power figures to a degree, although i would have expected the QST re-map to give more than a 30BHP increase, but i'm totally thrown by your torque figure.

Although mine has the AmD stage 2 which incorporates the Milltek sports zorst along with the engine & gearbox re-map, my output figures (repeated twice) gave close to 515bhp & 460lbsft both times. The power i can understand, but such a difference in torque between the 2 cars seems unusual. I have 460ish & yours nearly 560lbsft. How can this be when my BHP is slightly higher than you quote?

I understand that re-maps can be configured differently to allow for customer requests in the way the power/performance is delivered i.e huge boost/bang or a more gradual but sustainable power curve, but the torque figures quoted for your QST MTM set-up & my AmD set-up seem too far apart.

Rather than talking from experience. I have read on various forums over a long period of time (too much free time at work ) MTM remaps tend to have a more aggressive torque curve, and the AMD power figures as far as I have heard, tended to be on the optimistic side. Hope this goes some way to explaining the difference.
