A big oops by me. I would have sworn that I had set my ECU to use throttle position and not MAP. Well, I didn't. I was looking into a setting that Haltech has for "MAP Prediction/Fuel Film Enable" when I saw that I had left "Fuel Load Type" set for MAP. So that's nearly 150 miles running based on MAP. The only problem I had was odd behavior at low speeds particularly starting from a dead stop. I changed to TPS and drove it about 15 miles with no low speed problems. But I did notice that deceleration could be a bit too quick. More settings to tweak.
