Has anyone run this style of injector setup?

Has anyone run this style of injector setup with the stock computer? I have a 98 rcsb with an L31. I would like to stroke it to 383 add headers, port the heads and swap the cam for something in the 220° range and attach a 900 hp capable pro-charger.

Has nobody run external injectors with the stock 98 ecm?

I haven't heard anyone on here yet, but I have seen some on youtube. I want to do similar when I get better at tuning.

Sure, there been a lot of aftermarket designs. I've read about more of them in " Street Trucks " magazine. That would also provide you with a wider source of information.

Look for posts about the marine intake swap. You'll have to do the same things wiring wise. The pcm doesn't know what intake it's running. You'll just have to make the wiring work for the one you select.

You'll just need to make sure your injectors aren't low impedance. Mine are about 13 ohms and the PCM seems to like that. But if you're going to boost, you'd be r3t@rd3d to not 411 swap the thing too.

I have a friend running LS3 injectors on the BlackBox. The BlackBox does not like something with the LS3 injector data. I am about to send him a DBC P59 flashed with the Mexican GMT800 L31 based tune.

I did read some of the marine intake treads.
Will the stock black box be able to run without the mass air flow? Will the 411 swap be able to run without the mass air flow?
Thank You for inputs so far. Much appreciated.

Why would you ditch the MAF? Like L31 I run it more than GM did. It's more consistent when weather and altitude changes.

They can all run with the MAF deleted.
