Hello, My X4 Tuner does not give me the option to adjust the fuel pressure high enough for my injectors.  The most it will let me go is 30Lbs.  I need 43.5 lbs.  What do I need to do to correct this?

You would need a custom tune for that assuming that can be changed in the pcm. If you are seeing that as a preloaded option it is likely to adjust for 30lb injectors not for changing fuel pressure.
