The car is a mutt it has 82 gt nose body is an 88 all the wiring and interior is 92 gt with air bag

You don't need to bother with calibrated MAFs if you have the ability to tune...

Anyways, I would first increase the low slope a bit (say 15% increments) and see how the car responds. If that works but it doesn't drive well, pull it out of the MAF transfer instead.
