I installed the tune onto a 2007 Silverado with the 5.3L engine. Everything works fine up until about 35/40 mph when the ABS warning lights start flashing on the dash. The truck has slightly larger than stock tires (305/50R20) but this never happened before the tune. I tried inputting tire size directly, inputting tire diameter, changing the axle ratio, and also leaving it all at default settings but no matter what I did the ABS lights still came on. The inTune is fully updated as well.

Thanks.

Any idea when you might be able to fix this issue? I'm not really comfortable driving the truck with the ABS freaking out...
