I have the maxed size steam boilers, a 3x3x5 and theres are liquiducts connected to 12 industrial steam engines. I have been told by the wiki that the boiler can easily support 18 engines but now my engines are only running at 3 mj/t with the exception of the first two closest engines giving me 8 mj/t. 10 engines are running on 3 mj/t and my boilers are at 450 degrees. IS there away to get my engines to give me more power?
