i know about all the bad press going on at mbworld. i have a slk32 and im setting up a tuning session with tony from eurocharged/let and wouldnt use anyone else. if your in the atl area or close by ill let you know when are session will be and you can see the results for yourself. look at the sl55/65/ forum. those guys are getting sick power from jerry and tony. i mean massive!! 800+ ft/lbs torque on cars they said couldnt be tuned. and the best part is they wont dodge your calls. they answer all emails and actually answer the fone. try that with va&^% or vr(*
