I've noticed lately I'm not building as much boost as I have in the past. Sometimes when you stomp it, there seems to be almost two stages. It takes off good with a hard initial pull, but seems like sometimes it almost hits a second stage and the boost jumps up even more without pressing the pedal farther down. Which is where the performance was before. I have not changed anything with the truck but it seems like sometimes it will make more boost and power than others. You don't have to change your foot position on the pedal, it will go up to a certain boost and then out of nowhere it takes off again, almost like a two stroke. Has me stumped. I can't find any leaks or anything that would be changing and I can't determine when it is going to do it. Anyone have any ideas where to start looking. Tymar intake(new filter), TS Performance chip, Banks power elbow, and 4" exhaust. It has plenty of power but those few times when it does this it has a whole lot more than normal. Also seems it may be running a little higher on the pyrometer than normal too.
