Scrambler 1200 Xe Canned Tunes

I saw on utube a video about dnk tunes . you tell them what mods you have done and they send you a tune via a phone app or you can send them your ecu and they flash it for you. The main reason i would consider this, is the infamous lean condition of the stock tune. could a tune alone fix this lean condition or do i have to eliminate the cat also. bike is a 2022 with the cat in muffler, so aftermarket muffler eliminates it. Im hoping to avoid the tuner and dyno thing as we don't have a motorcycle dyno in the area. advice appreciated. Thanks , Tim
