many of the new computers don't have a "chip" to burn, which is why there's not very many guys trying to rework the ECM's anymore. As I understand it after talking to the guys at Street Performance, the new electronics, like for the LS engines, require rewriting the whole program and takes a very knowledgeable 'puter guy to get past the security stuff first, then make the program work right.

The older style like you have Gary do have a replaceable chip---but the whole system is already out of date. For the street, this new stuff is great! If you could find someone who can chip yours for towing the way the new LS engines are "tuned" for performance it'll be great!
