BG is a very good product...

I think this will become a routine maintenance for me and use seafoam through the brake booster or maybe even forget seafoam overall and do a MMO piston soak(I heard those are good)
Overall I am quite impressed and will try it on some other cars to see what results I can get.
Nice disclaimer. It's the equivalent of putting on the flame suit.
OP
I'm of the impression that stuff is pretty strong,so if you are going to suck it in through a vacuum line I suggest inspecting the cylinder with a plug out just to confirm you've actually got a deposit issue. Otherwise there really isn't a confirmed problem and you might be throwing money away trying to fix a non existent problem.
I like seafoam too however if there's more than minor deposits to attack seafoam just isn't strong enough to be very effective.
As far as mmo goes by accident I ended up testing it against tc-w3 for cleaning the stock pistons that came out of my Harley.
They guy I bought it from put a junk fuel pack on it to richen up the fuel map. In 12000 miles there was a significant layer of carbon on the piston crowns from the map being richened up in an attempt to cool the combustion temps but the reality was there was a constant incomplete burning condition which just caked rock hard carbon to the crowns.
I forget if I accidentally spilled tc-w3 or mmo on the first piston but after a few days sitting the deposits that previously required a belt sander or angle grinder to remove wiped right off leaving a clean,dull looking surface.
So I purposely tried the other product but this time,since I'm intentionally pouring it on I completely covered the piston crown,insuring the rock hard deposits look wet and the product absorbing into the deposits.
When I went back to my garage the next weekend these deposits wiped right off with a simple shop towel.
These results led me to conclude an mmo piston soak will certainly soften up hard carbon and may even improve ring seal if they are coked up.
An mmo soak needs a few days for sure to soak. Seafoam is very thin and I think it would seep by the piston rings whereas mmo is a bit thicker which translates into the fluid seeping slower which means it sticks around longer.
Give it a shot after you've confirmed there is an actual problem.
I use an inverse oiler in my dd so deposits just don't accumulate anywhere
Thanks for sharing your experience with the bg.
