Changed the oil, filter, fuel filters before leaving for a trip yesterday. Stopped for fuel at about the 200 mile mark. Soon after noticed an odd shudder. I may have been there before the fuel stop, but not when I left home. I was towing my gooseneck.
Only time it does it is light throttle,(slightly downhill rd) While trying to maintain constant throttle position the Fuel rail pressure was jumping from about 7200-8500 with a light shudder. Everything else was normal. Idle was 5k frp, smooth as can be at any other rpm or boost level. Running spartan 250 tune. 500 miles later, its still doing the same thing, not better or worse.
I was just going to reload the tune and try again. I was just curious if this was a sign of a sensor or something in the fuel system failing.
