Trucks acting funny.

Hey guys, lately I've been noticing my truck starting to hesitate, or almost like it's miss firing or surging. when I'm warming it up and it kicks up to about 1100rpm it does this as well and it really rocks the truck back and forth. Then yesterday I was driving around 80kmh and at 1300rpm it started doing it again. Any suggestions or ideas of what's going on?

you allowing proper time for the motor to warm up before getting on it? sometimes a cold motor would hesitate and sputter.

yeah, I always let the truck warm up good before heading out. I was running the 275 tune with the flopro exhaust. I changed the tune down to the 210 and seems to be running better. I don't think my truck likes the 310 or 275 tunes.
