3S-GTE Aftermarket ECU/Gen/Market Motor, Questions and discussion Options

[DEATH]

My main reason for this thread is to get an answer to these questions but I'd also like to hear from people who have experience and/or are running off an aftermarket ECU on their 3S-GTE's.

My Motor: 93' JDM GT4 3S-GTE [2nd Gen] *possibly RC edition cause CT-26 is the JDM Ceramic - yes I know this means nothing but it's possible - will find out soon into this discussion*
Mods are listed in my profile but it's basically stock with upgraded to:
8.8:1 Pistons
ARP Head Studs
HKS Metal Headgasket
HKS Turbo Timer
Blitz Blowoff Valve
Front Mount Intercooler
Custom Welded IC Piping
APEX'i Induction Kit/Filter
AFM/3" Intake/Turbo Inlet [minimal bend]
Custom Full 2.5" DP/BP
3" Magnaflow High Flow Cat
GReddy SP2 Catback Exhaust
Kirkasaurus Poly Motor Mounts
NGK Iridium Spark Plugs
MSD 8.5" Superconductor Wires
MSD Blaster 2 Coil
ACT Stage 2 Clutch
TRD quickshifter kit
TRD Boost Gauge
KOYO Racing Radiator

And I have an SAFC-II from my last Celica that is already setup to drop right in my new car and it does have various preset tunes built in for the various ECU's.

Goals:
Daily Driven [not really but built for]
Retain/enhance the Celica's already legendary handling [Ie. no drag racing setups]
275-300WHP/300WTq
Reliability/Engine Safety
Easily Adjustable Boost Levels for DD/Track/Just messing around - basically 3 levels 10PSI/12PSI/15[+?]PSI
Stock Turbo
Fairly civilized demeanor with low RPMS/Monster-ish when pushed hard
Low 13's consistantly on GOOD street tires
NO ECU's that require all adjustability to be done on computer/dyno [I want some options - SAFC-II's dual saves and easy adjustment is acceptable to me]

Questions:
1. What are the available P/N's for ECU's [both MR2 and Altrac/GT4] for 2nd Gen from market to market: JDM/UKDM/USDM ?
2. Are there P/N's different from market to market: JDM/UKDM/USDM [I assume so since tuning is different]?
3. If there are different P/N's will there be different options or any limitations I may run in to when selecting an aftermarket ECU/Piggyback.
4. And lastely/most importantly should I even bother worrying about another piggyback/standalone ECU when the SAFC-II I already have is perfectly sufficient for my fairly low expectations [or is it? You tell me]

I'm not afraid to upgrade the fuel or timing [seperately from the SAFC-II or integrated into the ECU] like a bit bigger injectors, it'll definetely get a full MSD ignition etc.
One thing I do like about the SAFC-II is the customizable readout and knock response.
What do you guys think? I'm def not trying to build Tufy's car here - just an extremly beautiful and elegant sleeper to make living in a driving intensive spread-the-fcuk-out town/state like Houston/Tx more enjoyable.
Thanks guys.
