If you've got high HP goals, then make the investment once and get the bigger injectors.
You lose nothing with having larger injectors.


Personally im running 82lb injectors, on a 340lph, and shooting for about 450-500whp on e85.

That's what I assumed. How do you know that percentage or is it the way an injector is setup or tuned....I've been a BBC carb guy forever and never really seriously modded ls engines so I'm learning still.

So by logging your meaning when ur tuning? I appreciate this help I'm trying to square this away my Hp goal is 750-800. I'm trying to decide if I want to dabble in tuning I've had two mail order tunes and am not happy with it. Plus adding this turbo everybody says find someone that knows how to tune LS turbo vehicles. I asked for a quote from Speed iNC. for when I install turbo and fuel upgrades but got nothing back.

Tuning, is a process of modifying the parameters within the ECU usually to accommodate for new changes, I.e. larger cam, new heads, long tube headers, and so on. It's often done based on the data collected while logging.

Logging is taking data samples as you drive under different conditions to see if the changes you made are correct for your combination.

Tuning is done with an editor program while data logging is a scan tool program.

Both are separate programs used together when you buy a tuning suite from one of the few companies out there.

Hope that helps!
