Brassring, Do yourself a huge favor,don't let it sleep,spend the $168 to get the pump calibrated and governor set by a hyper,certifyed cummins,robert bosh diesel pump shop.Your warranty will still be in effect.We recomend you ask for lee at Midwest diesel,Ft. Dodge Iowa.Hyper tune"d cummins run under 100 gallon fuel_day useage with power a non issue.(the old 670's would burn up 150 gal._day)As slugs hit rpms actually pickup with a snarl.On the go dumping just causes further vengence to boil.A beast sleeps within.Bottom line there are many different torque curves available.lee sets it with extreme balls. Good luck! Hyper
