I have purchased a MK 808, TS 401 and autel programmable sensors. With all this will I finally be able to program my tires to a setting of 50 psi as they require and have the truck accept it without the low pressure light on the dash? The truck came with 65 psi and the new tires are BF KM2 which are same rating but lower pressure. Also, why does the 808 not support the tire change feature on the 808? Should I just return everything?
