I know we unplug vacume, but is it just along for the ride? The Ford MAF kit uses AHACA strategy that is supposedly shared with BIO0 and HOG0. Both have a single oxygen sensor like the AHACA. I noticed that 94-96 F150's and Broncos with a 302 and MAF don't even have a Map/Baro sensor under the hood. These 302 trucks have the HOG0/BIO0 calibration. What's the deal here? Tuners inside please.
