    Thanks joecar, I got the scan tool and tuning tool on the same page. I can track the correct cell now. I got some adivse to try raising the timing in the areas with knock. It worked! I put the stock timing table back in, then began to add timing in the areas that were problems. Between adding timing and removing fuel it fixed the knock pretty well. I still get a little bit, but it is in isolated cases now and nothing like the knock I was getting before. I re-scaled the injectors again, correctly this time. The MAP sensor is scaled, and my VE is being touched up right now. Thank you all for the help, I have learned a lot in this diagnosis.
