No Mileage Incresae After EFIE
I have 2000 Grand Marq 4.6 2upstream 2downstream. I installed 2 smackboosters Put 3.9 resistors on the IAT,CHT,and a20 on the ground for MAF. Installed EFIE and set to 200 to start.I was monitoring the o2s,SFTRIM,LFTRIM,Fuel injection pulse,Loop on the snap on scanner while making adjustments.Drove 30 miles and moved the EFIE to 250 and drove for about another 40 miles. Adjusted to 300 and drove while watching the scanner. The o2 was going from 300 to 1200 but the injection pulse is not slowing down at the same speed while driving. still in closed loop. still running fine no lose of power.Any advice to make the fuel injection slow down.

My suggestion would be to start over at 150mv and just check mileage. I'd adjust the efie in increments of 50mv at least a few days apart.
