Stock Injectors vs Swamps Stage 2 Splits

Does anyone have any experience with the Stage 2 Splitshots from Swamps? Not looking for 400 hp but slightly better than stock would be good. I am not interested in singles because of the ecm programming. Basically if you had a choice between the two what would it be?

Re: Stock Injectors vs Swamps Stage 2 Splits

You will need more hpo if there is a big nozzle.
You will need new tunes to run a larger split shot as well to make any exra power.
I didnt even no there was still such an animal available.


Not even sure what makes it a stg. 2..... And not require tuning as they state ?

Re: Stock Injectors vs Swamps Stage 2 Splits

Yes I already have a chip but you can't just run down to the local parts store and get another one thats programmed for singles. If something goes wrong with the chip I want to be able to pull it out and still have a good running truck. This truck is a my only truck and can't afford to have downtime waiting on another chip if something happens.

Understood, guess thats why I have spare chip and pcm for each truck. Also so I can send the spare out to try different tunes. Never had reason to use the spares yet.
Talk to Dave , I believe he would burn your chip if you decide to go with Swamps.

You can also get your PCM burned for singles so if you have a chip problem your not dead in the water.

Re: Stock Injectors vs Swamps Stage 2 Splits

Thanks for the responses guys. I've tried to research these splits the best I could and haven't found a post on any diesel sites about first hand experiences with these. I'm not going to buy something that no one else has used besides the manufacturer. Guess they might not be such a good idea afterall.

I just had my pcm flashed with my best running tune as the j3 port fried. The down side is if i want a change, i have to send the pcm in. Im going to pick up a stock pcm one day just to make tuning upgrades easier, this is my second chip with issues due to the pcm. Im kind of done with plug n play chips. Especially when i go to singles, i dont enjoy sitting broke down, though theres a low percentage of guys with chip issues on the other hand.

Singles are really the better way to go, more power, less hpo, easier to tune, less smoke, less heat and better mpg.

I beg to differ. That comes more from an "old school" train of thought.

If you can get the same amount of fuel out in 3 ms rather than 4 ms on an identical injector.... which one is going to require more oil?

Which one is going to smoke less?

Which one is going to have cooler EGT's?

Split-shots are only oil hungry because of the inherent nature of the split-shot injector AND the amount of time it takes to empty them given the stock nozzle size. Eliminate the restriction of the nozzle size, and reduce the amount of time it takes to inject the fuel, and watch your HPOP hold pressure easier than before. Then you get the side-effects of less smoke because you aren't dragging out PW longer than your injection window, and you have cooler EGT's because you're burning the fuel within that injection window rather than continuing to spray it when it's not doing any good.

It's still going to use a bit more oil than a single shot, but it's going to make a big improvement given proper tuning.

Ehhhhhhh.... let's reword this.

Throwing Stage II splits onto bone stock tuning will automatically make extra power. It's because you now have more fuel available in that same amount of PW that the tuning is calling for.

What should be stated is that you need new tunes to run them PROPERLY. Pulsewidth is going to have to be scaled back with larger nozzles.

Yep, they've been around for years. They never became popular because of the common tuning applications years ago, which more often than not consisted of throwing gobs of PW at the injectors. Do that to larger nozzles, and you end up with a smokey pig that eats up all your oil and asks for more. Tune injectors with larger nozzles the right way, and you get more power with less oil usage, and smoke can be kept under control and even end up with less smoke than stock nozzles as your power needs increase.

Stage II is typically a nozzle change. There can be more to it than that, but typically it's going to a larger nozzle. Just like singles are often labeled as Stage I and Stage II, with Stage II being the exact same injector as a Stage II but with a 30% or 80% nozzle (depending on the builder, but this is applicable just about across the board).

They state it doesn't "require" tuning because it will run and idle fine on stock programming, contrary to trying to run single shots on split shot tuning. However, it can cause a more touchy pedal and more smoke. If tuning is adjusted properly to account for the larger nozzles, that smoke and touchy pedal can be eliminated.
