I hvae looked into the chaos for the timmy since I will be getting it here soon for testing.
From the looks of it it is better than stock. It has all the options that any other aftermarket board has, but you can also change some settings via vlink, which requires a vlink cord to plug into your computer. But it is included in a board package at vaporworks.com.
It will allow you to change the way your max rof works. You can either set it for max rof, or actually just program it to limit it to a certain bps. And a few other modes can be messed with as well using the vlink.
I dont know what to tell you if it will fit in a 06, since I dont own a 06 timmy, or a chaos yet. My main concern is if it works with the rf chip.
