I think any self tuning software (with A/F input) will be only for normal light load driving. Any high load (WOT) driving and you will have to set up manually.

Atleast this is how I see a lot of aftermarket computers on the market. Please do chime in pro's if im wrong.

Holley EFI has those options, but installing that in your car would require a retro fit that replaced a lot of the stock equipment or lay the new EFI kit over the exisiting wiring somehow to power all the support equipment and keep all the standard ignition and stuff.

You're going to want to put that thing on a dyno to tune the spark table any way you slice it. There's no good self tuning option for finding optimum spark timing on a blower motor. For your build, you will be better served by hiring the best tuner money can get rather than the best self tuning system - a good dyno tuner is going to be way ahead of the computer.
