At idle truck is missing.When you apply throttle my truck stutters like loading up the more throttle the more missing and studders then picks up and will pin you back in seat.when you ease back off the throttle it goes to misssing again until throttle applied.Any ideas what this may be?

Have you loaded a tune on it ? Did you do a boost bypass mod ? Did you do a TPS adjustment for any reason ? Under throttle when it feels like it is missing, does the CEL ( check engine light ) flash ? When was the last fuel filter change ? Have you changed out the plugs to a different spec ( usually with a tune change, if specified ).
What engine is in this truck?
