what would be the best uel pressure safety switch (what psi would i need)
setting up for a 75-100 shot of nitrous
engine: 98 ls1 t/a

 

any FPSS deisgned for a an EFI vehicle will work....you can set the pressure to shut of at after install.

Remove the bottle from the car......Take the fuel line off the nozzle....have an assistent hold the fuel line into a catch can.....bring the vehicle up within the RPM window and activate the kit......slowly tighten the adjusting screw until the sytem starts to pulse/shut down, then back the screw off 3/4 of a turn.
