Gen2 S550 Idle Slowly Increasing

[miiiiitch]

Procharger car with locked out cams. On e85 everything was working perfectly. When I changed over to tune on 93, I started getting some very weird issues. First, the MAF table needed massive adjustments, which I didn't expect from simply changing the stoich. Now, when you fire up the car it's extremely lean, until it suddenly decides to clean up and all of the sudden fueling is correct. The idle is right on the 1000rpm commanded. Then, slowly, the idle rpm increases until around 1800rpm, where it seems to stay. No vacuum leaks that we can see. Any idea what could be causing this? Log and tune attached.

how old are your O2 sensors

O2 sensors are pretty old. I have trims turned off, because they don't seem to be working correctly until I start driving the car.

I just don't understand why it idled fine on e85, and then I change to 93 and now it's acting crazy. I also had to pull like 30-40% from the maf table, which also makes no sense.

Before you touched the maf table how was it running?
