Put my mind at ease, or don’t?

Need some outside perspective. 
 

I wanted to the give the Crosstrek a tune up, an oil change and a carbon clean using Subaru top end and carbon cleaner. Yesterday I put in the carbon clean through a vacuum port directly on top of the intake manifold using one of the orange hoses you get in one of those fluid hand pumps found everywhere. I slowly siphoned the 11oz our of the can as directed going 1/3 at a time and then revving the engine "above idle" until everything smoothed out. The hose is pretty large on the vacuum is strong so I pinched the hose with my fingers to limit the amount of fluid it sucked up at once and I didn't just shove the hose in. I'm aware of hydro lock and I was trying to be careful. 

Anyway, yesterday I did that and everything went fine. It hiccuped a little when the fluid went in and because of the massive vacuum leak but everything seemed to go well. 
I drove it to work today and didn't really notice anything. Slow as usual. 

Today after work I tried to put in the top end cleaner the same way. But today I could not keep it running. The idle would fluctuate the same way but it would stall continually. It took me twice as long to get through half of the bottle because I couldn't keep it running. It would crank back up but not quite as quickly as normal. It also threw a CEL and various other related lights. 
I gave up at this point, put it back together and drove it home. It ran fine, slow as usual, but actually seemed a tad smoother. When I got home I finished the bottle but same thing. Once I opened the restriction on the hose it would stall or hiccup really badly. Very frustrating. 
Once the bottle was empty I put it back together and drove it around. Seemed fine but I have a fear I can't shake that it pulled too much fluid and I broke something. I cleared the codes, did an oil change and it's sitting now. I'm going to monitor over the next few trips and make sure everything is normal. 
it doesn't really make sense that I broke anything but it's our good car and I want to keep it that way. 
Ive never even seen a hydrolock, and I really don't think I put enough fluid in to cause anything like that, but it is a subaru and ya know, they don't need a reason to blow up. I'm hoping the stalling and misfires were from the vacuum leak and not too much fluid. Right?
 

Anyone want to give me another opinion? I'm having trouble with this one. 

Hydrolocking takes a decent bit more than gently siphoning fluid.  I think you are safe there.

Until I get a dissenting opinion I am going to say that the procedure went so well and so smoothly that you improved the health of the motor enough between the two days that it was actually affected by the vacuum leak.  

Anyways, don't drive like my brother.

You won't hydrolock anything doing that. No worries there. I bet it's fine. I'll even second what asa said. It's probably better than it was. 
 

of course, Subaru being Subaru, it may have spontaneously junked a gasket. Or something. Good luck. 

I did a spray can of direct injection intake cleaner in our Mazda 6 a while back. The directions were all about holding rpms, then heat soaking, then running blah blah blah...  The first time I tried to drive it after that it would barely run, threw a code, and went into limp mode. After getting it home I unhooked the battery for 20 min to clear the codes and short term trims and such. Ran fine afterward. 
 

but I know nothing about subies

I understand the paranoia, I get that way too. As long as it continues to run and drive fine, I wouldn't worry about it.

My buddy hydrolocked his Integra back in the day. AEM cold air intake plus driving through a puddle that submerged the intake is what it took.

Damage was immediate.

Your fine, I wouldn't worry. 

If it was hydrolocked you'd know it. Immediately. 

I'd probably disconnect the battery for a few minutes to give the ECM a reset but just driving around will work for relearning (if anything affecting run conditions actually changed.)

Yeah, DW hydrolocked her 2.4-swapped Neon even with the shortened Iceman intake on it.  Don't put a big puddle between momma bear and the cubs on the only open road to daycare.  It was lunched immediately and hard.

I'm with the "reset the PCM and you'll probably be fine" camp.

Thanks everyone. I cleared the codes and drove it around and it seemed fine but it's one of those times when I have to convince myself that I've heard that tick before and it's always been this slow and....

I can spiral quickly. I feel better though, thank you!
