NC IL I80@68 | A good 4020 should run 95 - 100 , you got the fresh overhaul , injectors checked , when was the pump last checked ? How did it run before ? Under full load there should be some smoke . What do you have now for smoke should have some when throttling up . Also any air restrictions etc . Are they dynoing it at right RPM ? Wide open throttle 2375-2425 RPM pulled down to 1160 PTO rpm . | |
