FiTech EFI system

Thanks Ken,
I will give that a try but now I've got a new issue. I had the Dart out on Friday heading to a cruise when it just plane started cutting out. I was just cruising heading to the gas station as my gauge was on 1/8 of a tank when it started acting like it was out of gas. I made it to the gas station and filled it up but the car just kept acting the same. Luckily I was only a couple of miles from my house and managed to limp it home having to restart it about 15 times. When I got it back to my garage I discovered that it wasn't only under load but in park as well. If I raise and hold the throttle to 2500 RPMs it will come up and then after a few seconds the RPMs drop and die like it's running out of fuel. I figured it might be that Tanks Inc (Walbro 255) pump as I read about a lot of people having trouble with them. So I went to Summit and bought a Aeromotive 300 LPH pump, dropped the tank and replaced it. Well as luck would have it, no change. I've e-mailed Fitech, we'll see what happens.

I would watch your map numbers at the time you get that lean issue when getting back on it.. You may be at the point where fuel is being shut off. DFCO cut fuel map
If you are, then try lowering the dfco number to slightly less than what the MAP numbers say. Bring the DFCO return map just above the number you set the DFCO Cut fuel map to.
There is also the DFCO return fuel setting to consider
