Default 08 F150 - Backfires and sputters

2008 Ford F 150 in generally great condition with 104,000 miles and a 5.4 litre engine. The engine starts fine and runs great once up to speed but during the initial take off the engine stutters and even backfires. Once speed gets to 25 miles or so the engine smooths out and the truck drives great. No codes. Any advice? Thanks

Standard first question... Have you replaced the plugs, springs and boots?
