FBO 335 JB4 Switch to map 4
Hi all took my 335 out last night its FBO auto did a few pulls everything seemed fine then I did one more before I went home and the Jb4 bumped me to map 4 from map 5 checked to see if there were any codes. No codes were thrown but it said my last safety (or map 4 switch) was due to Fuel pressure being to low. I just replaced the HPFP 3 weeks ago! What else could it be LPFP sensor, LPFP? Any help or assistance is appreciated.

I was not able to catch the switch to map 4 in a log but here are the links to the two logs I took today. Let me know what you think.
