Mass Air conversion questions
 

The kids are grown to a point that I can get back to my Mustang. I am ready to convert it to mass air. I have some questions.

1) I have an 88GT 5.0, 5 speed is the computer I need a A9L?
2) Does it matter that I have a GT40 intake (ported)?
3) I want to skip to a larger then stock Mass Air Meter to match my throttle body. Will the A9L computer work with a bigger mass air meter?

3:55 gears
stock injectors
High Flow cats
2.5" or 3" exhaust (don't remember, its been awhile LOL)
fuel pump is not stock

Thank you in advance
