I thought it might be interesting and helpful if we started a thread to share what Edelbrock Pro-Flo 4 owners have been using since the system seems to have become so popular in these parts.
Please refrain from criticizing or critiquing unless it's asked for. The idea here is to just provide some information that might help others dial in there systems. There is not right or wrong answer.
I'll start with mine. I struggled for quite a while with mine wanting to die when shifting into gear when the engine was cold. For a while it would shift fine cold, but then wasn't doing it warm. It seems to be working well now and I think it's a combination of AFR, RPM, and timing.
With the TH350 (no overdrive or lockup torque converter) I'm getting an average of about 13mpg with a low usually around 12.25mpg and a high around 14.3mpg.
If anyone else is interested in posting their info, feel free to copy and paste my list above and just change the numbers where appropriate.
