Try resting your throttle position and then give it another test, another post said the same thing that it was not a big difference until the throttle position was reset then it came to life.

Installation of the throttle body was easy - like described by TVT some posts earlier - no problems at all. I took some pictures and maybe I'll write a short walkthrough within the next days. It took me only about 30min. while beeing really careful. The engine started like nothing happened - no unusual reactions.
I got mine frome eBay - there are several available over here in germany.
Usually you guys in the States have all the fun stuff - but for buying used Mercedes parts living in germany is quite an advantage.
I already have the Mercedes V8-Airbox installed - currently with really dirty stock airfilters because I didn't receive the correct K&N's yesterday... Apart from that my engine is stock.
Regarding the difference: There is a slight difference in sound and the throttle response improved a bit. I drove about 10miles on the autobahn and I think there is a little more power on the upper end too. So far I'm happy - especially regarding the effort and costs - although I don't feel the difference as much as others described it here. Maybe I'm just not sensible enough for this car yet - I bought mine just one month ago.
Next projects are larger injectors and ecu tune (maybe both from TVT if there is a way to get everything overseas).
