You do not need to program a manual for new gearing. Speed is taken from the wheel rotation sensor hence takes into account all gearing, just need new diameter of tires. If the pressure is above the original setting, set at 32 on my stock 08 JK, then the light should go out if the sensors are the correct ones...if they are not the correct sensors, then you have the option of changing them, listening the chime and looking at the light, or using a Procal or such, turning them off.

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
