1990 Pontiac 6000 *AWD*, 7730, 3.1 V6. The AWD's retained the vacuum operated EGR when other apps went to the "digital" EGR. What mask do I have? My dad just bought TunerCat to work on his Cad 500 Suburban and 400 TPI Jaguar, both with 94/5 LT1 controls (8051?), so I figure I might as well get the appropriate definition file for my 6000 and kill the EGR off.
