that's if you can find a dealership that will fudge the paperwork enought for you to get them changed out under warranty its $2400 for a set of over sized ones so thats not bad the FASS fuel system is only $600 so all in all $3000 for having a stealthy truck isn't to bad. but thats only the start of my plans exterior wise i'm keeping the grandpa mobile look to it

 

stock injectors will do 650+ rwhp easy...

 

Concidering that your truck is stock I wouldn't reccomend bigger injectors. They are more for a duel CP3 setup that has more pressure and can keep the fuel rail pressure constant with the bigger injectors The 24V cummings is totally differrent. It has a mechanical injection pump. With the Duramax increasing fuel rail pressure and injector duration you can achieve alot. I would reccomend a PPE chip or an EFI Live tune and to put most of the extra money into your trans. Your truck has to 5spd ally and it will not hold alot of extra power.
