Yeah. Go to the CFM tech site that beater 20 posted and read the "GM TBI Tuneing" page with all its links in yellow.. It explains TBI function and how to best modify it and will give you a basic understanding of what you are working with.
Rember when working with TBI never remove or disable any sensors or the EGR valve. They are all vital to the proper function of TBI.
