I have a 95 Astro and after reading your story I was looking at specs on your car (stock) and we have, or had, the same wieght, transmission (4L60E), engine, almost, I have 4.3 v6 yours had a 4.3 v8 option, and same towing rating. I wanted to just be able to get 30 mpg highway. I think with our vehicles being fairly similar and you getting 43-46 mpg I should be able to hit 30 with mine, despite it being less aerodynamic. Im planning on doing aeromods though. I would like to do a manual swap but that'd be a long ways away.
