Forced Induction Injector size for supercharger

all new/legit one's aren't? like Siemans, FR ones...

No. They are all manufactured to a standard but that standard could put one at the top of the scale in the same bank as one at the bottom.

Matched sets will all come with [flow sheets] and are usually grouped with injectors that are within 1-2% of each other.
 
Everything I'm finding says their house brand injectors are chinese brand. Lots of poor idle, stuck open reviews, and poor customer service. They do sell genuine Siemens, but all out of stock like everyone else. I think I'll keep looking.
wow. Just called them and they said they do some with flow sheets. I asked them about the ones that say bosch/siemens and they didn't say out of stock so I'll call back and ask as to if their house brands come with flow sheets. I just googled 60 lbers yesterday and it showed those at their site but i didnt look at others at the site.

But all in all if the reviews are bad I'll definitely not go with a house brand and only want to stick with FR or siemens anyway. Might just have to go FR and use the adapters if can't find siemens or no eta on them coming in. Gotta make sure with the adapters there are no issues as connectivity or coming loose, ect. I read something where some had issues either with the adapters or the pigtails or something

I've been using the FR 47lb with adapters for years without any problems. Putting in a new motor this winter is the only reason I'm looking for 80lb. I might just bite the bullet and get the FR again.

Oh I see, seems you prefer the 80's siemens without having to use the adapters but ok with the FR's if you have to
