Opinions on Megasquirt/ thread locations

I'm thinking of using this system on my 88 Spider and I know ther are a lot of threads on here regarding it, but I was having trouble locating all the info I wanted. If somebody can advise me or point me towards some threads regarding the pro's and cons of this, how hard it was to install/tune, where to find software, and what major issues I may run into with the spider, or why I should use a different system, etc. I would appreciate it. My goal is a measley 225-250 fully streetable, turbocharged HP, then I'll move up from there if necessary.
