I was just wondering what the stock injectors can handle.I'm going to be running a t3 setup at 8psi.

Thinking about using FMU with the stock injectors is why I'm asking.

Any exact numbers on how much they can handle with and without?

You can run 4-5 psi with no management using the stock injectors. With the FMU you can run about 8 psi but you'll need to retard the base timing 2 degree's just for safety.

Retard 2 degrees at 8psi?

Also what ratio would you recommend for that?

Thank you WD you're awesome about this stuff.

Just retard your base timing at the dizzy if you're going to mrun more then 7 psi of boost. That's what I meant, when you run 8 psi and keep the stock 20* you might knock some. By removing a few degree's you're just adding some room for safety.

I'd use a 6:1 FMU. The 8:1 is going to be a little rich, which is ok, but why bother if you don't need to?
