I don't know what is meant by " tuner boy" but I stay away from any backing of CF that is painted. 1. It's not needed and the back showing carbon confirms the process...at least for me. 2. it adds weight ...it defeats the purpose of CF.... 3. if painted....it's probably because they used fiberglass as backing and tried to hide the fact. Also, I treat this part as a wear item. My car is dropped pretty low and is aggressive for most and I bottoms out at times. I will have to replace it in time. I gave you my info and opinions....good luck.
