do these things come set in a ballpark range out of the box? Im doing heads/cam right now and it was on my mind when I installed it along with my new injectors on the fuel rail.

 

You can't assume that it is set to any particular pressure.... you need to put a pressure gauge on it, and verify that it is set exactly to the pressure you told your PCM tuner you were going to run. Anything more or less, and you are screwing up his tune.

 

Thanks for the reply, I know it will come down to me putting a guage on it and seeing what its set at...I was just curious. Ill have to give a call to fastchips to see what pressure they were going with when they did my programming. thanks again
