I also have a Banks system and couldn't be happier. It really woke the truck up. I would call Banks directly and tell them you circumstance. We had a Ford that we installed a new kit in and never got any increase. What Banks found was that every time they had brought it in for transmission work, they reprogrammed the ECM. When we got it, it had a code that they had never seen. Two or three weeks later they had a solve for it, a new chip.
Now I know that the 92 cummins is different than a Pherd, they have been very helpful with problems. They seemed to go the extra mile.
