My dyno results from an ECU custom map from DMS Automotive on my 2002 SL55

Thought you might be interested to see what results DMS Automotive got from a remap only on my standard 2002 SL55, I'm really happy with the results, plus the way it delivers power is so much nicer, and good to have that limiter gone too for my next Germany trip!

Nice figure for a standard car. I assume you have had a pulley upgrade as well to make that figure?

Hey, yeah Im pretty happy with that! And no, that's just a map, no other mods at all.

77mm Supercharger Pulley - MSL Dyno Test | AMG Lounge

Hi All, As some of you may be aware there is a new 77mm Supercharger pulley (twin bearing) available from MSL and manufactured via UPD. It offers the ability to match the power / torque figures of the tried and tested 180mm crank pulley and as such, potentially offers owners a new pulley to...

To get 552bhp from just a remap on an M113K engine is almost unheard of.
The above thread shows a similar engine, with a good remap and an 83mm pulley making 567bhp.

I'd check that pulley of yours. To get 552bhp it must have been upgraded.

Something's not quite right with that graph, power & torque always cross over at 5250 rpm ...it doesn't on either of those runs?

I just looked back at my old E55K and they do cross over at 5250 on that...

Isn't that the case only if the scales are the same for both power and torque? The scales on that graph are different.

5250 is only the constant for imperial figures iirc? Mine are shown as PS and NM, not HP and ft/lb (where 5250 is the constant)

Edit: Yes, the calculation for metric is P(kilowatts)= (T * RPM) / 9549, whereas Imperial is HP= (T * RPM) / 5252

Edit 2: Also entirely possible the graph has been scaled, I'll call them tomorrow to find out

So, looking at the calculations in more detail, its a gain of about 40hp and 30ft/lb (roughly) which seems about right for a remap only

Yes I think that's the reason
