Injectors!

Hey guys, I am rebuilding my injectors soon, i think I'm going to do the 75 horsepower nozzles. Do I need a tune to run those? And will the stock fuel pump keep up? I believe I can go 40 and 50 hp also. Also if anyone has done this what programmer would you recommend pairing the upgraded injectors with?

Post a link to what it is your talking about.
Most injectors are not sold by HP rating

Injectors are not rated at hp increases for our trucks. They are rated buy size, ie 160/30 or 175/80. They are also rated at a generic stage 1 and stage 2 ratings. What do you want to do with your truck? Do you tow? What's your goal hp rating? What's your budget?

yikes, we better help this poor fellow before csipsd gets ahold him of him
HEUI injectors are very different than most injectors. there is a lot of internal parts that need to be modified and then flow checked to make sure they are all similar. otherwise you can never have someone tune the truck right.
like sbluke said, we have different size nozzles, 30% 80% and higher


the 75hp injector thing is a cumminGs thing

Party pooper.

He's probably in the shop modifying some more Stage 2 intake spiders.

I use the truck for work. I tow a lot. Right now the truck is stock. My main goal is good fuel mileage out of a tow rig. But if it's fast to then I'm all for it. I found a site that sells a kit to rebuild and modify the injectors to flow more and they have the horsepower ratings for each stage

Listen closely, do not buy a DIY kit, and do not buy from whatever site that was.

The injectors used in these trucks are a lot more involved than cummins injectors.

Swamps, Power-Struck, PIS, rosewood, and full force are the big guys that come to mind.

For your application I would suggest a 160/0 or 160/30 from any of the above builders.

With proper mods that will get you 350 to 380 horsepower or so

Okay so say I get my injectors built by one of these companies, do I have to run a custom tune or can I use a can tune or a six position chip. Are the injectors even worth doing? as of right now my injectors have to come out and be cleaned up
