Getting ready to tune a 6.0 we built in a 2000 silverado. Weve got 8.1 marine injectors and from what I've read there is no hard data for them. I've seen a lot of these injectors get sold in the classifieds so I'm hoping someone has some good data I can start with. It's a n/a setup with a return style fuel stock fuel system. I'm using hp tuners. Any help would be great.

What size are they?

The 31lbs or the 42lb/hr?

That might help more so someone could tell you what to you. If they are 31lb/hr you could look at a factory 8.1 tune for information.

The 42lb marine injectors

Go to the tune repository and pull the data from an 8.1 tune file

All the truck files will have 31lb/hr though, not sure I've ever seen 42lb/hr in the tune repository. Mainly because it's a marine injector.

Try that file - you may have to be logged in to get to it. Did a little research and the marine style injector is popular with the radix and other blower kits.
