100w are plenty. 130w may or not be better, tbd.I have thought about increasing the bulbs in mine as well. I have two sets and the original set came with 50's which I upgraded to 100's. I have a custom wire harness that should handle 130's I'd think. Didnt know there were 130's!
My advice is to try finding bulbs with 4000kelvin temp rating. I put 4000k halogens in my headlights and never looked back. It made such a difference!
