Occasionally when I go Full throttle my truck will act as if there is some sort of governer on for a few seconds and then it will finally open up and go as it should. It appears the boost is increasing properly according to the Attitude. I've experienced this on all Juice Levels. Not sure if it's fuel delivery problem or something else.

Possible turbo lag combined with your fuel filter getting dirty.

The Edge boost guage is worthless IMHO. Definately turbo lag.
