Damaged Banks Chip, running poor

I have a 2002 F350. I noticed when it had a Banks Big Hoss mod under the dash when I bought it but thought nothing of it because I don't know much about diesels. Finally after two years of decreasing MPG I checked it out and the corner was cut off the mod; I was informed by someone in the know that it was cut to destroy it. My MPG's have been steadily decreasing, down to 10 now, and the pickup is sluggish. How do I fix it? I thought using a SuperChips tuner to erase the computer program and reset it would help, but it didn't. Any help would be appreciated. Thank you.

I don't know what you mean by the corner being cut off of it. But, to fix it, simply remove the chip. That will put you back into stock setting. From there, you can buy a proper chip with custom tunes and you'll be feeling much better.

Get some pictures of what you're referring to being cut off. If it's part of the ECU housing, that's normal, and won't affect anything. Since you've been noticing a steady decrease in performance, I'm guessing something else may be the culprit.

It looks like someone used a grinder or cutoff wheel and cut the corner of the chip off, through the plastic housing and through the internal circuitry. You can see copper that's been cut through inside. I did take the chip out and the performance seemed to get worse. I was hauling a gooseneck trailer, total maybe 8200 gvw, and the mpg were 10 or worse and going up hills it was going 45 mph with the throttle mashed.

A fellow I talked to after pulling the chip said just pulling it wouldn't return to stock programming, and that I could either get Ford to flash the PCM or order another Banks module.

I thought maybe a SuperChips tuner could wipe the memory bugs from the damaged Banks module and reset a better program. I towed the same trailer yesterday and got 12 mpg, but anytime it would really start to pull it made a sound like spitting before down shifting. Every time it would pull hard the check engine light would come on. One time the PTC was something like "could communicate with control module" and another time the PTC was something like "ICP pressure undesirable."

Pulling the chip will return it to stock. It's the biggest difference between a chip and a programmer. If the chip is cut in half and still connected to the PCM, it *could* be sending bad info to the PCM. Whether it's THE problem or not won't be known until you pull it. It is definitely not helping you since it's broken anyway.
