If anyone is interested, I just swapped out my 2007 C230 Sport for a Chrysler 300C and before I give up the Benz to the new owner, I pulled my almost new Sprint Booster out of the car.
I bought the Sprint Booster from a guy on these boards about a year ago but the unit has maybe 700 total miles on it. I never drove my Benz. Its got only 1200 miles on it total right now. The booster came to me right from Greece where its made and was about $320 I paid.
Anywho....the Booster works flawlessly, is easy to connect and it does make a significant difference in accelerator lag.
I can send pictures of it if you would like but its pretty much just a wire with some clips at the end.
Make me an offer if you are interested. I just want to get rid of it since I won't have my Benz as of the end of June.
I had it in a 2007 C-230 Sport with auto trans. I am not sure if it fits other cars or not. It will ship out of Tampa, FL. I am not shipping outside the lower 48 US.
