Hi everyone,
I have a question regarding Gen3 Hemi fuel injectors. My current injector DC is well over 80% (88-93) on WOT pulls which from what I understand is not "recommended".
Q: Should I swap my stock injectors for a DW 525cc? Note: I plan to go for LT headers and a cam soon.
If yes, how are the new injectors tuned/dialed in? These PCMs do not have an InjPW Vs Fuel Mass tab on the Editor.
Any ideas/suggestions for my case, assuming I need to go for bigger injectors?

You could just get some used 392 or hellcat injectors for pretty cheap. As for the tuning, can you post your file, i might be able to help find the parameter
I agree with this…
Injectors from 392 are easy to dial in.
You can run injectors up to 100%, not the best but it works.
Otherwise you can raise fuel pump voltage/loss
Hello James,
I was thinking about getting the 6.4 Injectors actually, and now you've made up my mind lol
You can find the tune file on the first post :) Thanks!

But I think I don't have the parameter you mentioned as well.
Maybe you can steal it from a 392 file….mostly fits.
Then dial in injectors

here is your tune with stock 392 injector data
also, thats alot of timing, are you getting knock?
I already have a stock 392 file, but it has a parameter called InjPW Vs FuelMass and I don't. That's why I was having trouble figuring this out.Quote:

It should have that table or at least the inverse. Post both files here or email them to me. Email address in my sig.Quote:

I will be attaching my files here. I am logging knock and advance and I did not find anything concerning. tbh I'm not 100% sure if I'm logging the data properly but everything looks fine.Quote:

You are right, I apologize to everyone for the confusion this is my fault as I forgot to switch the editor parameter view to advanced *facepalm*Quote:
