I have a Blitz Access Supercomputer for a 90 to 92 mr2 turbo. It is tuned for 540cc injectors as well as a ct20b turbo. I bought it a few years back for my car, as I was told it would also run with 440cc injectors. While it does run with 440cc injectors, it is absolutely pig rich. 8000rpm redline, remapped fuel tune, fuel cut raised to 18psi, and speed governor removed. Plug and play, easy installation!
