first of all get gauges if you already donthave them, (at least a pyrometer). try sliding you stock fuel plate forward a bit, you get some more powerout of that. is that is not enough then a #10 plate and 3k gov. springs will definately liven up your cummins. if that is not enoguh you may need injectors, but your auto transmission wont handle that much power, and youll need to upgrade. happy bombing!
