I've got a 98 auto truck in the shop now with ddp 50's 215 manual pump, 4k gov, 64/71/13, factory afc springs and slightly loose factory afc settings, housing slid foward, 100 plate in the middle and I can puff a fairly dark little cloud before spool up, but at spool it completely clears all smoke and egts quickly come back 800-900 wot. Hope that gives you an idea of the amount of fuel available With 50 horse sticks.
