Performance chip
I remember several companies offering a chip back in the 90's to alter the ECM of your vehicle for performance, been looking for something for my 89 Econoline, just to bump it up a bit, OBDII you have the ability to reprogram them, IDK what I can do on the OBDI. The mountains here really slow it down, some on the floor you do good to keep it at 55, I'm not looking to win a race, just give it a little more power, I've yet to tune it up, has a miss, likely a vacuum leak, old lines probably rotten, will be replacing them too. I like the 300/6, more torque than the 302.

I did see you can increase the fuel with injectors from a 5.0, I've yet to see where the suggested timing should be set, and I do want a hotter coil, missed out on a MSD box a while back. We are bothered by a miss at the moment, I've just yet to pull the doghouse because it is caulked shut with sealer, not thrilled with that, when I do pull it I want to get everything done in there all at once, complete tune up, and new vacuum lines, I was just curious if there was a way to retune the programming on it.

Not a good idea. The stock tune is more than enough to get as much power out of the motor as it is capable of making, it is not holding it back. The stock injectors are also capable of supplying more fuel than the motor needs so larger injectors won't accomplish anything but poor gas milage.
Factory is 10deg before TDC with the spout plug removed to disable computer advance. You can try advancing it a couple more degrees beyond that, every motor will be a little diferent in how much timing it will tolerate so test the motor under load for detonation. If the base timing isn't set correctly the motor will be down on power from where it should be.
