Hey guys I have done a pile of mods to the ol 90 cummins but I know there is more HP to be had. I have cranked the fuel screw, backed off the throttle stop, did a fuel pin and 3200 spring. I need to get the most out of this pump for the dyno in a few weeks. I cant get my 14mm pump here and on in time so....what else can be done internally for the most flow? Is it worth pulling the afc lever? I need to break 400hp or preferably 500hp with nitrous. Please post all your opinions and recomendations. Thanks.
