Injectors 4.8 vs. LS1

[6gear]

I am using a 4.8 intake and injectors on my LS1 and was wondering what the difference is between the LS1 and 4.8 injectors, also will the 8.1's work and is there any performance improvements.

The difference is just a few points. The 8.1L are 30lb's.

If you plan any mods, I'd say it's a nice improvement and possibly needed , depending on the mods.

I was running the truck injectors, then went to the 8.1 injectors. I didn't notice any improvement.

later,

Thanks, I didn't know if I was starving the LS1 using the 4.8 injectors but it sounds like I am not.
