I have an older 16 position thumbwheel chip. It says Caspers on the bottom. Thumbwheel and chip are in great shape. I will list all of the chips that are programmed into it.

The chips increase in performance as the list goes down. I had this in my car since I bought it and it worked great. I just checked Caspers website and they are selling just the blank 16 position thumbwheel for $109. With this, you not only get the thumbwheel, but you get 16 chips allready burned into it. It is possible to burn your favorite chip into the thumbwheel if you wanted to. E-mail me an offer. thanks.
