He is more in range now. But he has a pretty big range: 80-200. (Which on shots we were 100-200). They said we'll watch how it is over the next couple months and probably dial down the top of his range to 175 or 150. We are still seeing the occasional 350 which kind of sucks, but I'd say 4out 6 tests per day he is in range.
We are working on figuring out post-meal highs right now, so I am monkeying around with various basal rates. When we started he had 1 and then after the first three days they added a different basal rate for the evening - which helped with bedtime highs. I'm an engineer by training, so I kind of like this 'problem solving' part of it. (Though, don't get me wrong, I would like it a lot more if I didn't have to do this and my kid didn't have T1D!)
We use the inset 30s, which are spring loaded, we didn't even try anything else cuz he's so thin. I like them, they're pretty easy now.
My perception is that you will be able to get your son's numbers down gradually, but in a pretty short period of time. I know from reading that teenage years can be hard because most other hormones increase BG. But again, it is easier on the pump to correct for highs and you can give tiny amounts. Where as on shots, there were times that he would be 250 and we were supposed to give 0.5 units but wouldn't because if we did a few hours later he would be crashing low. Now on the pump, I can give him 0.25 units and I know it is accurate and on the next check he is in range. So that makes me feel better that we are correcting as we need to, but now over correcting.
