I dont... there was that one car vid comparo vs the M5 with the comp pack and they did dynos where the E63 had 540 at the wheels... but we all know what dynos mean. The trap speeds in the quarter were slightly lower than the M5 in that test. I think the AMG is slightly underrated though but no way 100hp.
My local tuner just did an E63S and they got 588 AWHP but I have to clarify if that was with dp's or not.

What was the AWHP before the tune? In reviewing a number of threads that discuss tuning this seems to be something most, if not all tuners, somehow avoid stating. If you are going to change or "improve" something, it really is scientifically proper to know what the starting point is. Then each change can be measured and documented (on the same dyno, of course).
Just my 2 cents worth.

Lets not assume there wasnt a baseline because I didnt mention it:
baseline was 508awhp--- tune took it to 588 awhp and now I confirmed 610 awhp with downpipes. So the tune was about 80 awhp...

I agree, Ive been tuning my cars for over 10 years and always do baselines (if there was one available)

So with a 508 awhp base it looks like the stock motor is a bit under stated adding the usual 20 percent drive train loss for AWD. It pencils out to about 609 hp at the crank or 32 above the advertised 577. More is always better than less.

Its dyno and operator dependant though.... I take stock in only before and after dynos to see what gains are from mods. Id much rather have the car that is faster on the street and slower on paper; I had one like that in my 2004 E55 which had some lower dyno numbers but would beat other cars like it that dyno'd higher. Dynos are conditional to say the least so it all depends and as for DT loss that depends too. Some say the MCT should use a lower percentage and others say higher. I dont know what to use but if one wants to claim more crank hp just turn up the DT percentage LOL.
