Ive hit the fuel system brick wall in my shadow. I hit 210 on stock injectors with the stock exhaust and now that I have the 3" downpipe and a fairly restrictive muffler I have lean spots all over the place. My next upgrade is +40s and a cal but first is the fuel pump. I drive a 1990 and that is my problem, How do I know what fuel pump to get in my transitional year. Some places say 89 and down and some say 90 and down for the old pump. Is there any way to tell externally on the sending unit what version it is?
This thing will be fun after its upgraded more. The power came fast and I wasnt expecting to have to upgrade this fast. What Ive read on here made it sound like it was so hard to make power with these cars but this came easy. I cant wait to see what happens when I get to the motor internals.
