Hey guys. So my goal is to have my Cummins pushing 600RWHP safely. I am slowly on my way haha, not even close though. So far I just have my deletes done, S&B cold air, and Smarty JR, 4" Turbo Back. Just wondering what would be the best upgrades/mods to reach this goal? I am definitely thinking of changing programmer to either a H&S or EFI Live, but I am not to sure how EFI actually works. Does it come with pre programmed files or do you have to download/buy them? Next is ARP studs of course. Then I was thinking a FASS system with 90HP injectors... Now what brand of injectors to go with? Then what, bigger turbo? Again who to go with: ATS, BD, ect... Thanks guys.

 

If you order EFI live from a company that uses it to calibrate tunes you would be buying an Autocal with tunes written for your truck ready to flash.

600RWHP goal will be needing the supporting modifications intake, exhaust, lift pump, race fuel valve. From there we will need to make sure the transmission is addressed.

I would not recommend to upgrade your injectors, the turbocharger is your next hurdle to overcome. With these upgrades you are going to be right around that 550-600RWHP mark.

 

600 hp is not a real hard goal to achieve with the 6.7. Just make sure everthing behind it can hold your goals then ho above its addicting. My wife hates my truck
