Uneven Acceleration?

Hi guys, was wondering if anyone could help me with a problem?

I've got a BA XR6T ute with a bit of work done to it. For some reason it won't accelerate smoothly at around 2500-3500? It feels like the throttles coming on an off?

It boosts smoothly after 3500. I've already made sure there's no boost leaks. Any help would be great...

incorrect throttle modulation input?

Post up a dyno graph if you have one

the before and after fuel curves do not look like something I would expect from that workshop

My reply is only 7 years late to this topic, but I had a similar thing happening and it still does to my car after a fairly large round of mods and a tune. It turns out it was traction control kicking in when it sensed a very small amount of wheelspin. Feels like it's surging and if you watch the boost guage it boosts up then drops down then boosts up etc etc, turns out there's nothing wrong with it. Turn traction control off and go hard, just be careful! This may have been your problem.
