I was going to reply to your introduction thread but I feel that this is where I should post my query...
So is it detuned or just rated less on paper? I have heard about the intake restriction on the passenger side and exhaust restrictions too. UCU programming? I have seen the exhaust and I don't see anything that could restrict other than maybe pipe diameter? I would like to know if it is true that it is 469 HP vs 493HP. Just curious, that's all..Thank you.

Well Shaun, the E55 is not detuned, or I would not call it detuned, the AMG factory spend countless hours on tuning every engine to their max power possible and still be able to be reliable. You might look at the torque output on every RPM through the whole power band, due to weight and transmission of the vehicle, plus purpose of the vehicle, the 230(SL) is a sports car, so they want you to get a lot more response out of the vehicle, while the 211(E-class) they looking forward to make the vehicle more comfortable to drive, due to the fact that this are still luxury vehicles, and even though you have a full race engine that can pass emissions, there is a very large customer demand for luxury and comfort in the US, while in Germany they still sell E-classes with no power windows and manual transmissions, I really dont know the reason why we cant have some of those vehicles here in the states. But this is one thing, look at the price differance between the SL55, S55 and E55... SL55 and S55 are vehicles that their price tag was around $140,000 while the E55 was sold for around $75K, so the factory actually was putting more time on fine tuning the 220(S-class) and the 230(SL-class), while the cams and pistons may cost almost the same, those vehicles are sold for more money because of the time AMG spent on tuning them, and too bad they didnt put the same amount of power on the E55, like the way they are doing now with all the Black Series, but dont feel upset about it, the E55 still can race against the SL55, just look at the power to weight ratio of each vehicle, and their power band, SL55 is a luxury vehicle with a race engine for the road, so its purpose is to make different torque at different RPM, even though there is a horse power differance and price tag differance, the E55 has its advantages over the SL55, plus in Germany they have their different race applications with this two vehicles, now the S55 is the heaviest, that is ment for the people who wanted that extra power on the road, but the S55 still can perform well when it comes to corners, all 3 vehicles have a different geometry on their suspension which give them their advantages on different applications, and by that I mean different race tracks, when it comes to time attack, like how tight or how long the corners are, even the track elevations and road conditions, how much under-steer or over steer you can get, so some times the factory even lower the power at a higher RPM just to let the car be able to perform well in certain conditions, but you still have the chance to tune your vehicle the way you want it, its just that sometimes more power is not the key, perfect example is the SL65 compared to the SL55, SL65 is way faster than the SL55, but when it comes to corners the SL55 is a real challenge for the SL65, and with a long corse most likely the SL55 will come victorious. I hope this have help you to see things in a different way and Im sorry if I couldnt explain my self better, dont pay attention at the high numbers, but start to look at the torque through the power band, how much torque and power the vehicle can output at the wheels through every RPM. Just to let you know, the SL55 outputs more power at a higher RPM, while the E55 have more torque at a lower RPM.
I hope this video help you understand why Mercedes are not ordinary cars...
