Guys,
I'm looking at upgrading from stock to Stage 1 injectors, along with a few other things in the near future (38R, DP Tuner) for under 400-hp towing gains. I've been trying to reserach the details of what the differences are, from info gained from a few differemt websites:

From RRD:

AC - Came in high torque version of the T444E and didn't come in any Powerstrokes. They have the same internals as the AB injectors with the exception of the single shot plunger and barrel and are 160cc.
AD - These are found in all late '99-'03 Powerstrokes and T444Es, and are a Split Shot Injector
AE - Long lead AD injector that was used to cure a "cackle" issue.

From Full Force Diesel/Casserly:
"94-03 Stage 1 Single Shot 160CC

Stage one reman performance injectors to increase the performance and horsepower of your powerstroke diesel. The injectors in the 94-97 Ford Powerstroke will increase horsepower from 50-100hp to the rear wheels with a performance chip. In the 99-03 Powerstoke diesel you will have to run a custom programmed chip to make the transition from split shot injection to the new single shot injection. Horsepower increases from 50-75hp and mileage increase from the more effecient single shot design."

So, by reading this, Can I safely say that-
1) for my stock 2002 truck, I should have AD code injectors, possibly an AE in Cyl 8
2) The Stage 1 injectors from FFD flow the same 160cc rate as the hi torque AC injectors,

Does this sound correct? Basically, the Stage 1 single shot injector is a AC injector, correct?

 

Exactly. Only key point is you will need tunes to run the ac codes(aka) stage 1's due to them being single shot where yours and all super duties came split shot. Just like you said.
Maybe there are a few vendors that tweak the ac codes and call em stage 1.5's or something but I know casserly (full force) is straight ac codes. These injectors will suit you if you can be content! Specially with a turbo and tuner. I made 345hp with basically the same setup. Honestly to me it seems like way more power than I can use. Egt's get crazy when pulling heavy!

 

Pulling heavy is what I'm planning to do- not in the next few months, but probably by next year getting a larger RV.

I want to add some more power, but also keep EGT's in check- I'm only really looking at a couple very mild tow tunes from Jody, and probably a general econo tune, but would like the turbo and injectors to accompany it.

What kinds of EGTs were you seeing? Did you dial down your tunes or injectors after seeing the higher temps?

 

This is in a 80hp tune.

David, dont scare anyone...my 80econy will tow hot,thats why you use tow tunes..I towed appx 13000 (when pulling triples) with 60 tow tune and never seen anything like that... Full Force stage 1-160cc,38R turbo normally 800-1000 long steep hills if i didnt let out of her 1350-1400....

 

what turbo are you running in that video? what was the weight? have you upgraded the i/c at all? the 80e tune shoots the egt's up there unloaded i cant believe you actually tow in it?!?!?!?!

 

mike whatever the code designation is for the sticks youll love stage 1 injectors....i run swamps 175/146 single shot stage 1's and love them...matched with my h2e its the perfect setup...i also run a tapercore intercooler and have nice fuel system upgrades and an adrenaline hpop....all that combined lets me tow relatively cool and gives me plenty of power....

 

AC's and a 38R are great!

AC's and a H2e would be better!

 

About 27,000#. Before live tuning. If it made a difference. I haven't pulled the same load since. Them 3:73 gears don't help, plus my 285's!

 

ok with that weight it doesnt seem abnormal anymore.....why does your dually have 3:73's? you put those in there?

 

No. Came like that from the factory. Matches my factory tag on axle and vin code. Definitely a disappointment! Thought it would make better fuel milage but not.

 

38r for the turbo
