vacuum adjustable fuel pressure regulator question

I was wondering if i could benefit from a vacuum adjustable FPR with the mods in my sig., im trying to figure out ways to hit 14.999 before i swap in a 350 this summer.
I was also thinking about doing a TBI spacer, and maybe removing my seats and endlinks at the track. Is there anything else i could do.
I have already read the long post about the vAFPR but i did know know what mods the people had that were using it, so i just want to know if it would help my cause for 14s, thanks.

Try a good set of sticky tires. If you could get your 60ft time bellow 2sec's you would probably be in the 14's.

I wouldn't recommend getting into it unless you swapped cams or heads ( something that would really require more fuel and air).

yeah, thats what i was thinking, but i just wanted to make sure, i guess ill just get a tbi spacer, do a little weight reduction for the track and try to lower my 60' times.
i also was thinking about making a ghetto cold air around my open element with some duct tape, cardboard, and 3" ducting hose and routing it where my brights are, well see how bored me and my friend get during spring break. THanks guys
