anyone running a zex kit on an ls1?

I'm wondering what zex's bottle pressure recommendation is. I was thinking I'll probably be safe just running between 900-100 psi.
I haven't hooked up my wideband yet but I was wonder if a/f ratios stay pretty consistent throughout the quarter like they are suppose to with zex's "special" nozzle or does it get rich really quick?

ZEX suggested bottle pressure is 950psi....A/F ratio will fluctuate depending on actual jetting and bottle pressure, just like every other kit. The ZEX kit has no way of monitoring A/F ratio and adjusting the mixture during the run.

Don't take this as saying the ZEX kit is bad, as it is still a very nice kit, and is the easiest to install.
