hey guys, I am having an issue with the car going rich when I shift, and also rich on tip in. I have rochester 1000cc injectors, I know my scailing is close, the worst i have seen the trims is negative 4 %. I think fixing this problem should be in accel enrichment but I am not sure which way to go with it. right now im just using the stock values. any suggestions? how many ppl even mess with this?

The car should still be tuned theoretically. To clarify i had it tuned then 500 miles later debris from previous engine damage wiped out a rod bearing. When I rebuilt the engine I purposely didn't change anything that would effect the tune, The setup stayed exactly the same except for I used different connecting rods and fresh rings.

Any help is appreciated. i am semi familiar with ecuflash, and have tephra modded several cars just never did any real tuning.
