Looks like I need to get on board with this PCM stuff. I know there are alot of threads about this on the SSR board so I guess I need to get started reading.
* When you get the custom tune are you in essence receiving an overall performance enhancement of which a number of settings are changed and enhanced?
* Are there specific things you need to ask for when having this done?
* Does this void the GM Warranty if you still have one in affect?
* Thought I read some keep their original unit and purchase a new custom tuned one and others simply send theirs and have it updated and returned.....pros/cons?
Thanks.
