[QUOTE="rocknmj, post: 1547269, member: 15427"] I guess that makes sense (I remember seeing the multiple "hot" fuel curves), but it seems weird how it will go straight from say 13k psi to 18-19k psi instead of spooling up gradually. I'll just keep watching it, especially as we move into the cooler months ahead. I did also just have a whole new engine bay harness installed that finally fixed another rail pressure issue I have been fighting on and off for the last 10 years! Thanks for the input.
