Hello all, I apologize if this has been addressed but I am in a bind. I am looking for an ECU programming device or something similar to add HP to a CL550. I recently purchased a Juice Box Stage 3 Plug n Play for my X6 (BMW) and am looking for something similar for a friend for his CL550 as a gift. All of your help is greatly appreciated as I have had no luck searching online and it's getting way too close. Ha! Thanks!!
