That's the weird part-it happens at exactly 50kpA manifold pressure. I can simulate driving by using a trigger wheel simulator and operate the MAP sensor with a hand operated vacuum pump-the PCM will kick the AC compressor clutch off at 50kpa. If I pull a little more vacuum, the clutch will lock back in again.

As far as all the files, all the current patch code is included in the XDF, as well as what it replaced. To patch the bin, Start with the Rev3.01 patch, then the 2-bar patch, the wideband patch, and the fuel injector voltage patch, in that order. That's exactly what I have running in the truck now-I haven't changed them in months.

There is an N/V ratio to consider the truck at WOT and disable the A/C, but it doesn't seem to matter what I set it up to, the 50kpa switch point stays the same.
