Performance nods arent really worth the cost. You dont add much and it cost a lot to do. You can change impellers and get my take off thrust, but lose top MPH. I like the way my boat is performance wise.
My mods include:
Audio System
2nd Battery and switch
interior LED's
Voltmeter on dash
Hydroturf
Polished out and buffed the whole boat and added new decals.
I just spent a ton rebuilding the trailer. So I am done for now. Only other thing I want to do really is get a Poppy cover and maybe add a bimini top.
