It could also be that the action of the bolus shot is not being matched by the influx of glucose into the bloodstream from the meal. In other words, the glucose supply is peaking before the insulin action. If, for some reason, absorption of the insulin is delayed, you can expect to see your BG go way up shortly after the meal. And it will come crashing down again later, when the bolus insulin eventually gets going.
Testing your basal dose will reveal whether this happening. If it is, you can then experiment with different bolus timing and/or changing the GI of your meals. Obviously, the more carb you eat, the more demanding this matching process is. The more insulin you inject, the more variability you can expect in its action. But you should be able to keep the post-prandial peaks below 9.0, even with a carb-heavy meal.
