Without tune, would a 2006 E55 be 469 or 500 hp? And with euro charged tune?

AWOL

E55's tend to be underrated. They typically dyno in the 415-420whp range on a dynojet. That being said, were looking at ~500 crank stock. A tune probably nets 25 whp, so say 40 crack = 540 crank with tune.

Thats just my opinion, on both research and experience.

I dyno'd 410hp & 444 tq at the wheels stock, but I'm not sure how much exactly i lose from crank to wheels.

This has been covered so many times before, just use the search

Mercedes quotes 469. Where did 493 come from?

That is the Mercedes quoted HP for S & SL class cars, the E got the same engine. The marketing department thought it wise to under rate the E.

I believe this has been discussed repeatedly. There is some information that the S and SL class has freer flowing exhaust. Regardless, factory position is 469. Clearly many cars are doing better.

For what it's worth, I made 417whp and 453wtq on a Dyno Jet, bone stock.
