This may be the stupidest question ever but if a twin turbo engine is tuned to lets say 14psi and a single turbo engine is tuned to 14psi. Would that be like tuning the single turbo engine to 28psi to match the performance? If someone could explain how that works it would be greatly appreciated.

No...

Are you saying that there is a TT engine @ 14psi, the single turbo engine @ 14 psi and a single turbo car at 28 psi, it'd be the same hp as the other 2 (14psi cars) power wise?? If so...it doesn't work that way. There are ALOT of factors that come into play with this kind of question.

Than explain, I don't get it. Sorry I'm car stupid, but at least I know a shit ton more from when I first got my car. But is it a legit question or am I just super retarded?

Gotta start somewhere. It's not a legit question because it's not really that specific of a question. It is sort of retarded lol. but hey, like i said, you gotta start somewhere. In the automotive world twin/single turbo has it's pros/cons depending on your build/application BUT having a 1g DSM at 14psi compared to a Supra TT @ 14psi is totally different from an Evo @ 28 psi.

ok
14 psi single turbo talon >greater than or equal to< 14 psi twin turbo vr-4
i guess basically what im asking is, what is the difference in turning up boost on a single turbo vs. a twin turbo.

4 < 6. Obviously, there is more air going in/out in 3/S's compared to DSMs. 14 psi in a DSM is much more different than 14 psi in a 3/S.

14psi is 14psi, but 600cfm of air at 14psi is going to make more power than 400cfm of air at 14psi. That's how you need to look at it.

It also makes a difference whether the TT set-up is Sequential or Parallel.
