The stock mass air meter is your choke point right now.
The C'n'L 76 works really well on stocker builds. I ran one on a stock motor with full exhaust and picked up a solid 1mph and a tenth and a half in the quarter. I would recommend one for your build.
Back in the day when stock builds were all there was, a 65mm TB was tested time and time again to net 2-5hp on a stock speed density 5.0, which had no mass air meter up stream. With your build (cam and ported lower) I would speculate all of the 5hp providing you address the mass air mater first.
With the stock 50mm MAM there is no point worrying about the TB.
Whether it is worth it or not only you can answer. I ran a 12.96 at 104.0 with a stock motor, stock TB... full exhaust and 76mm MAM. With a 65mm TB maybe I would have ran a 12.8x. Had I kept that combination, I would have ported the lower, added a 65mm TB, addressed the suspension and gone for mid 12's.
I thought I already posted this, but I do not see it showed up. I agree the stock MAF is a real choke point. What is its size, only 55 mm? I changed the MAF (BBK), the TB and EGR plate (BBK 70 mm) at the same time and ported the intake opening as far back as I could reach. But the lower intake and E7 heads were already ported, the cam changed, a full exhaust system on it and a fender CAI (BBK). On my combo, the tires no longer stick in second gear. SOTP feel says it was worth it.

The 95 had 55 mm maf? thought it was 70? I'm working on a 95 not the 90 that my name refers to. Before the ported lower and cai(I know its worth 0 hp, just for looks) it made 209 rwhp with the cam in fresh motor and rusted out mufflers. Since then I removed precats and new mufflers, and ported lower, and 3.73 gears. Haven't done much to motor in awhile, been spending $ on paint and suspension
I have no idea on the 95, I was referring to the fox in your pic. Oops!
That makes the TB/EGR plate a better buy if you have the supporting parts.

Like I said a few posts back, best bang for the buck here in my opinion is an explorer intake setup, with fox body throttle body conversion and convert the 65mm tb to work on the mustang.
Fun little project for $100. With stock e7s, will be a worthy mod until you upgrade the heads.
