Ah, 88 - don't you mean:Yes I did and I editted them

Stock CHT should be around 204-208.
My canned tow was about 209-210.
My perf canned tune ran about 213.
My 87 custom perf+tow is about 212.
Anything above 218 (no weight truck only) cruising the highway.

(Cylinder Head Temps all in the "200s"?) And, those numbers are pretty similar to mine, unless I'm towing up some long steep grade where the transmission is down to 2nd and the RPMs are running near 4000.
