I have noticed the last few times that I have gotten on the freeway that my truck seems a little sluggish. I just did the injectors with new filter about 1k miles ago.

To describe the sluggish part, if I get on it, it feels like it goes pretty good. But at about 2800 rpms it takes off and goes really good.

My question is, could it be my FPR going bad? I know that I should put it on a tech 2 to say for sure, but I was hoping maybe someone who has had similar symptoms will chime in.

Mine is doing the same thing as yours. It seems like the brakes are dragging and then they just let go and it takes off like a rocket... what did you find? I'm still searching.

Mine doesn't feel like the brakes. You can watch the RPMs fluctuate right before it takes off. I'm hoping to get my commanded and actual fuel pressure tested to see if that is it.
