thanks, I plan to add more options for blower/turbo efffecy etc. Thats why i do have the assumed cfm listed and the assumed btu. It can only do so much when it does not know actually Ait and cfm. I did not want to run this off injector size, like another one of these i saw floating around. because what stops someone from shoving injectors to large for the app. You start getting into high hp per cubic inch and this gets off.
