I'm not sure if it's that big of a difference between them if any. How much lower? Did you have to do any mods using the l67 injectors and pre 2000 rail?

The red line of the 3400. With the 3400 you are starting with 40HP more before adding boost. The 3.1 was rated at 205hp with the turbo. You will probably be fine with 5-8psi and it will probably start choking the 3400 around 5000rpm.

I did not have to mod any thing for the l67 injectors with the '99 and older fuel rail.
