im betting that the maf is a bit laggy and its moving more air than you think.

And you are not running a boost referenced fuel pressure regulator?

John i'm running the 02' LS6 cam.

Denmah once you run out of fuel, a 1 to 1 regulator will help keep those 80's on par. The boost pressure puts pressure on the face on your injectors, limiting their output. Thats what the regulator takes care of.

Good luck man and keep it rocking.

I think the highest we've seen on the injectors is like 14 msec at 15 psi.

That's pretty good. Looks like you are only about 70-75% IDC.

What 80# injectors are you guys using? How hard were they to idle tune?

removed the block, helper spring, and stretched the shackles ourselves
