Hey guys new man on the scene I have a 2007 S550 5.5 naturally aspirated engine that I love big time! My nephew builds his own turbo's and I want to put twin turbo's on my 5.5 but I need a piggyback ECU does anyone out there know where I can purchase one? I have done a few upgrades new, spark plugs the S63 exhaust and it sounds darn sick made the car run much faster especially in sport mode, using the shift paddles, got the k&N filter today just haven't put it on yet.

So help me out there benz driver I want to have a hidden BEAST!
