And where does the BG settle at when the bolus runs out? Are you pre-bolussing as that on its own can help reduce your spike, the other concern is that your spike is probably even higher at 1 hour.

So essentially your bolus has matched the food if you end back where you start. If you are worried about spiking then I would (a) inject earlier so insulin is active when you eat (b) maybe eat less carbs (or eat them over longer period)(c) try more fatty food to slow absorption

40g is not that many carbs. Fat makes BG take longer to rise. For me 40g pure carbs would spike me by 12mmol, but Novo would take 3-4 hours, from injection, to bring me down by 12mmol.
If you imagine for example that the fat causes the food BG rise to take place over two hours and you timed the insulin so that it's two most active hours coincided with the rise due to the food then it woud largely balance out and hopefully no big spikes.

No wonder you spike so high, fast-acting insulins take around 15-20mins work so you need to inject ahead so that your insulin is active when your food digests.
Have a look at the following, it's a great article from the author of the book Think Like a Pancreas:
