I have a '05 F350 with 311,000 miles. Have done egr bypass (liberator performance) and have replaced injectors #2,4,6,8, and #3. Truck is sputtering on acceleration at higher speeds (60-70mph). Have good oil and fuel pressure. Truck has been to two different Ford dealers and no one can figure it out. Head gasket done at 212,000 miles and new ficm at 289,000 miles. Using amsoil oil and keep it changed and tested (no problems). Need some advice, PLEASE!!!

Did you put a manual gauge on your FP?
