I would install the stuff you have now, get a 2871R/supporting fuel & software and get it tuned then, since at that point you will need to be compensating for larger injectors and so on.

Yeah, thats what I'm planning on doing, or just get everything plus supporting mods ( injectors, maf, electronics, etc ) then put it all at once and tune.
