Mark and Chung were a GREAT help to me during the entire order process, right down to the install of my Lowering Module for my 2001 LS430 UL! Chung was very knowledgeable, and answered any question I had through quick email replies. Mark spent over an hour on the phone with me as I disassembled and reassembled my dash to make sure I had everything hooked up properly. Good Service, and great company! Delivered on time and had the knowledge to help me out.
