I was looking at the instructions on the txs website and notice that the abc that came with the UTEC i bought looks a whole lot smaller than the one shown in the picture. Sorry for the noob question guys, but i just want to make sure i have good stuff in my car. And if there is nothing wrong with it, do i use one real skinny allan wrench? Thanks for your help!

if i can remember correctly, the ABC's diameter is about a size of a nickle or a tad smaller. length is about 2inches? is that what you have?

yah, the small allenkey is what you use to change the setting.
ccw for more boost, cw for less.
