Since nitro burns at lower AFR than alky how much change to effect tune on nitro engine. In this case it is high volume almost for load A/Fuel. 40 gpm or 28 to engine with 95% load. Lets say a change of 500' DA what percentagefuel.Even if info is on smaller load with less flow info is always good to have.
