Based on your graph, setup, etc you re making the power you are supposed to be making at that boost level.

The choppyness is from the graph being on SMOOTHING 3.

CHarles mentioned CAM TIMING, not IGNITION TIMING. WHat charles (main stream) means is check your TIMING BELT to make sure it didnt jump a tooth or something, although IMO the graph looks too good to be a cam timing issue.

For a bone stock h22, with a t3/t4, prob a small compressor wheel, thats about right.

Id be happy, im sure the car is much faster
