I have an 03 Hemi Ram with the ABS light blinking after the tire size adjustment with the Diablo Preditor tuner.

13.18@105.83 with 8psi boost, full street trim and OEM 20" wheels and tires(275/55/R20).

Preparing for 10psi boost track run in full street trim.

NOTE: Had NO problems or adjustments done with this tune since 4/8/09.

The reason for the tire size change was due to the truck hitting the speed limiter just before the end of the track(105mph). The engine was also hitting the rev limiter(5800rpm) at each trans shift point. Was told there would be no problems with adjusting the tire size to possibly hold off the speed limiter at the end of the track. That's when the ABS light started to blink after the tire size adjustment.

I'm betting the abs module just needs a reprogramming by a drb3 like my truck did when I put the new comp in it and when they do it doesn't change the PCM at all but before doing anything save your tune on the computer

You can hook your predator to your pc in the house now and extract last tune writin and then you will have saved your current PCM tune to the computer for safe keeping

On the very odd time I've had to go to the dealer (ABS reset) I always removed my tune, even if it was in the parking lot.
