Bob, I have a near identical problem. Differences: 3.2 New rebuild 1200 miles. Swapped US P&C's for Mahle 10.3 &c's, FabSpeed Pre Muffler, SW rebuilt DEM (Motronic), SW Chipped for RoW/no Cat Converter, SW rebuilt AFM. '86 Cab 3.2, 63K original mile. By the by, the carbon track is very good...
I have been dicking with AFM, over 15 times in/put of car vs a loaner(better, but no real top end).
Lean and leaner issues. SW suggested pulling chip and R&R with factory. I'm not sure if it is "factory". I feel I am getting zeroed in slowly and methodically. Just a PIA plus to do so many swaps and resets. Wiper arm first, clock spring second. Fine tune with CO screw. I'm still on Wiper arm mostly and a little clock spring. At least I'm learning alot.
The point of the above is, today I ran a set up with silky smooth throttle response throughout the tach. I mean silky smooth. Below 4000 rpm all you could want. Above 4000 rpm NOTHING you would want. Extremely rich @ WOT, think high 10's on AFR. Tomorrow I move Wiper arm back down a couple of millimeters and loosen a couple of teeth on clock spring. Repeat. I have advanced the Wiper to max out on Carbon track (minus 1 Millimeter), and now will go less. Trial and error ad nauseum. Keep us posted please!
