Hi all, I just faxed a letter to Scott (Quick chip) to obtain more information about their products. Warrenty information, return policy etc..
As soon as I receive the answers, I will post it on.
I have also tired to contact superchip, and they really don't know much about Mercedes, so.... I my opinion they are not considerable. By the way, they only carry products for V8 and V12 engines.)
Thank you very much for the inputs! Especially to Benzmac and Lee, who always help me out.
Peter regards
