What vintage 91 do you have? If it is non IC, I'd leave the stockers in there and crank on the pump, adding an intercooler in there in the process. If you're intercooled, there are a few options out there. I have not heard much good about Diesel Care off ebay, either. I also havent heard about the injectors from the guy who claims 3-6mpg increase, depending on which injectors for which year he is talking about. But I have also gained 4 mpg by getting my stock injectors back to snuff.
