Dyno with ASP pulley
1st dyno is with johnson pump/K&N filters. 2nd dyno is with the asp pulley added. As you can see heat soak is a major issue. The torque increase is great but even driving the car you can feel the power hit a wall at higher rpms. The torque really dosent get affected by the heat but the horsepower does. Hopefully when I put my larger heat exchanger on I should get my hp back and alot more. Here is the link to my previous dyno https://mbworld.org/forums/w211-amg/238794-dynoed-my-e55-today.html

It's exactly as expected and discussed in the previous thread. You gain a little low end torque due to the increased boost but you lose power up top where the untuned ECU dumps fuel (look at the AFR dive just before 5K RPMs) and probably pulls timing too. Losing power doesn't seem worth it ... you need the tune. The load limiting issue has been well documented by Vadim in the VRP tuning threads I thought. I don't think the HE (although still a great idea) will change this picture.

My understanding is that it's on any car that got flashed by MB with the secondary air-pump flash. I don't know when the campaign started, but if your car has been to the dealer at all in a while it probably got flashed. You should in theory be able to dig through the records and find out if it's been done. I think it was a mandatory campaign that they would do pretty much without even asking you unless you very specifically asked them not to do it.
