The best thing I ever did with engine controls is the Holley HP. I'm running 25psi boost and never once did I have an issue once I got beyond Holley's ground loop problem.
The ground loop was an easy fix. I just grounded the EEC to the chassis right near where Ford did and where the block head ground is. Once I did that, and pulled the battery negative post EEC lead to the trunk battery, everything was fine. System is flawless.
I'm doing 1.3 60 ft times and running the Ford TFI dizzy with a CD ignition. I have a Bosch MAP/MAT sensor in the elbow, Ford TPS, and the rest came with the Holley kit.
I have the digital Dash.
It is an easy swap, and the best thing I ever did. I did a 20 mile street ride with no issues, and later in the day ran low fives with no changes.
