Ghost here. I'm have s few issues I need help figuring out. Im new to tuning but I learn quickly. I have an 82 c10 with a 5.3 Lm7 mated to a Muncie M/T. I'm about to purchase a new rd/bl ecm and I because I believe the one I have has issues. I'd like to start fresh so I could get my baby back on the road as soon as possible. I need all the help I can get. Thanks in advance.
