Bad a/f sensor AND cats?

After trimming 0.030" off the fuel rail spacers the injectors sat much tighter. There was absolutely 0 space for up-and-down motion and very minimal rotational motion.

Still leaks by :dammit:. I'm charging the system with <1psi of air and it's blowing by the injector's lower grommet almost as much as it was before.

Also for some reason it's only happening at the injector on cylinder 1. I also checked the one at cyl 2, 3, and 5 but can't really get to 4 and 6 with the supercharger in place.

I think it's time to take up Motorwest on their offer and see if that helps
