Final results. Improved throttle response. On cold days, it almost feels turbo boosted. The transmission stays in OD longer on inclines and kicks back to OD sooner after it has kicked down. City fuel economy slightly improved, highway mileage appreciably improved. At fill up after highway trip, the expected mileage on the odometer goes to 420, usually more like 360. at this point, I'm planning on keeping it this way until i find a better solution. So far pleased with my free modification.
