Nitrous bottle pressure

What should I be tuning the system for, 1000psi?

I ordered a few fuel jets for my kit. I am sticking with a 65Hp shot.
I got some 22 26 28 30 Fuel jets, so I can safely tune this bad boy.

I have a bottle heater and need to set the on/off pressure. I read that 97F will bring the pressure to 1000psi. This will give me good pressure in hot summer days without the need to cool the bottle. Should I aim for that. Or stay with 950psi. And end up having to cool the bottle in the hot summer days.....
 
I have a NOS heater system with the thermosats instead of the pressure switch. I believe they keep the bottle temp around 85 deg. This yields roughly 950-975 PSI on a cool night. I'd tune it for around 1000psi and see how things work. Monitor the wideband and go from there. My system is a little different since its the ZEX system. If the bottle pressure is low it automatically adjusts the fuel trim. I end up doing all my tuning via computer anyways, so if its a little lean, I just add more fuel. I've had a hard time trying to get fuel jets to give me exactly what I want for a ratio.
