W210 E55 with Supercharger on Dyno, 1st run

W210 with S55 Engine on Dyno. 1st run after engine switch, still a lot of things to do. 496HP / 761Nm on this run ... far away from what it should be :/ Engine should have around 600HP, but without the correct Fuelpressure only 496 came along ... next step, new fuel system. Engine with 172mm Pulley, 82mm TB, Kleemann Headers and RENNtech Software. Transmission is with Maybach Valves, M-Mode and CLK-DTM Software, thx to RENNtech for this great job! greetings
