Hey guys. I've got a 2007 GXP. I just started getting a code p0088 which means higher than requested fuel pressure. Has anyone gotten this code before? And what caused it? I'm able to read data with an MSD Dashhawk. I can't read fuel pressure, but I'm getting a catalytic converter temp of 1200 degrees driving in 5th gear at about 50 miles an hour. I've also seen the temps spike to 1600 degrees during 3/4 throttle accelerating from a traffic light. I'm leaning towards a failing pressure regulator in the HPFP, but I'm not sure. I'm hoping to get it fixed before I melt down the converter. Any help would be appreciated. Thanks, Eric
