P228D code, fuel pressure too high

I was wondering if anyone else has ever had this problem. I had this code come up one time before. I was at the track last night and had my car go into reduced power mode because of this. I have a 38% fuel lobe and a Lt4 hpfp, I used a lash cap. Is there something that needs to be changed in the tune?
