Pretty much the same way I've got mine set up, except I run a mopar stage II computer with a zener diode installed, which by luck idles fine with the +20% injectors. Here are my mods:
Mopar Stage II computer w/zener diode +20% injectors Full 3" exhaust (turbo back) NO catalytic converter 16-18 psi boost A568 transmission from R/T Car ran 13.7 @ 106 mph with 9 lights on the cyberdyne guage. Any more boost and you melt pistons, which I have painfully proved on my own. 18 psi is pretty much the uppper limit of the stock turbo, as any more boost will be generating too much heat.

I would play it safe and simple. I would buy at least a 190 fuel pump, cheaper than stock. Then I would buy a FWDperformance.com stage 5 87 computer for it. Get one just like I did, 18 PSI, +20s, 3 bar map on a fairly stock engine with just exhaust for pump gas. Then run racing gas and G valve it to 20 PSI. Extra injectors and pushing boost past the map is how you blow things up fast. If you want big boost you better get a 3" exhaust and +40s, then run 22 PSI on pump gas on a stock engine. If the engine is basically stock the cal is easy, you shouldn't need an AFPR. When you add mods it gets tricky, then you need the AFPR to tune it. A stage 5 computer with +20s at 18 PSI on a stock GLHS is the limit. Past that anyway your going to blow things up with light weight rods and a POS 525 trans. Hooked up to the turbo the computer can pull boost and timing if you get bad fuel, boost controls can't pull boost. I suggest. 87 Stage 5 FWD computer +20s 18 PSI on the computer, NOT the boost controller 190 fuel pump 2.5" exhaust with 2.5" swing valve larger wastegate can, unless it can hit 18 PSI now? MSD 3 bar map under hood map wiring change to run an 87 computer. Forget the AFPR, extra injector, G valve and the 255 pump. You hit 17.5 PSI of boost on stock injectors running the car lean towards melting pistons. The 2.5" exhaust will lean the car out and 18 PSI will feel like 20.
