Megasquirt is the only way to go nowadays for simplicity and ease of tuning.

If you're looking to get some longevity out of the engine, I'd say with your 99ron, you could run 15psi and for and 260-270whp for a long time on a newly rebuilt stock motor. By long time, I'd say 30-50k miles isn't unreasonable. Just don't get too greedy on the timing!
Your T28 can push more boost, but you're shortening the lifespan of the motor and tranny considerably. You also need to consider the differential. I'm not sure what UK spec Miatas came with, but if it's the 6" dif and you plan to drift, it will last about half a day before grenading.
