I have been having issues with my Fuel Rail Pressure dropping to 0 and back to desired. it does not always drop to 0 but it falls off, and i get a fuel knock. I have been running the same tune for almost 8 months now and problem just started 3 months ago. Here are some logs to see if anyone can help. I do not think its tune related but as tuners here i might get some insight on my issues.
I have upgraded my CP3 from stock to fleece power flow 750, changed fuel filters, changed fuel rail pressure sensor and went back to a stock tune. Still nothing not sure what else to check. I am running a Fass 220 and 100 hp injectors.
Any help would be very nice i am loosing it with this issue its driving me nuts.
