28chevys, you got me thinking, maybe my problem isn't that Im getting to much fuel but Im actually not getting enough. A 261 should be close to a 4.3L V6 262ci but you said you have a 5.0L throttle body on it with a 4.3L computer and it runs fine with the stock chip. Did you try it with the 4.3L throttle body and it did not run quite right? Maybe I should also try a 5.0 throttle body with the 4.3L computer?
But before I do, Im going to check all the sensors and make sure they are within spec.
I picked up a 3.1L computer and plan to see what happens when I mate it with the 3.1 injectors. My plan now is to also try it with the 4.3L injectors.
