Hi to all. Can anyone tell me why my cars run slower by nearly a second when i use the ssdc compared to the standard C7042 unit? I have got the power set to 100% on both the fuel effect and the cars power in ssdc but still they are slower. I have a long but fast layout with a 6 metre main straight and the performance difference is noticeable. I do have 2 power supplies and im currently only running 2 cars at a time. Any ideas?
