    What make, model, and year truck? How many miles? Fuel pressure is often over looked when trying to diagnose sluggish or no power problems. New fuel filter? Check or have fuel pressure checked. If it isn't in specs it will be a problem.

    Are you getting any detonation/pinging while accelerating under load? It could be the oxygen sensor. My truck was sluggish like you described and it was the sensor. I took it out and cleaned it very carefully and fixed my sluggishness problem. If you have a K&N filter and oil it too much it can give your oxygen sensor fits.
