At WOT the ECM on a TBI engine should kill the AC compressor til you back off the go pedal. Not sure if all of them do. It gives you a temporary HP boost for passing etc. My 76 has a WOT compressor kill switch on the 6.5L diesel. I installed it on purpose.
If this is not a WOT kill switch... you are describing an overcharged AC system or a failed or incorrectly sized HPCO switch.

This rings a bell. Are the HPCO switches adjustable? I seem to recall reading some info on something being adjustable.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....
Cubic inches is like Indiana Jones with a cheap pistol.
