Welcome! To help folks get you better answers faster, update your signature with some info on your build. There's a link on how to do that in my signature.
To answer your question, I think we need some clarification- the way I read your post, you purchased a completed Goblin with a 2.2 engine. Is it a manual or auto trans? And what is it you're ordering from DF?
If your Goblin was built off a 2005 or 2006 2.2 donor, then that computer is un-tuneable and requires a swap to even add a turbo to it. As previously mentioned, swapping to a complete SS/TC (aka LNF) engine requires not only a new computer but also new wiring.
If you have a 2007 or later 2.2 computer, I believe you can swap in the LNF block, exhaust and intake manifolds, and turbo, and tune on your existing computer. Hardly any additional wiring required. This is the general route

If you have an auto trans, there's additional work required, like a new DF tunnel cap with mounting points for the shifter, shifter cables, etc. I'm not up to speed on the computer and electronics side of that swap.
