Magnum and Wiring Swap

Maybe it was this article you saw? Not exactly dyno testing, but from a flow perspective the Hughes is still way better than the kegger. Testing intake manifolds for the 5.2 / 5.9 Magnum V8 engines

I saw that Engine Masters episode and was pretty impressed with the carb air gap. I think the Hughes intake is pretty much that with injector bungs, so the results are probably pretty accurate for EFI comparison purposes.

That was my plan... drive it and enjoy it for a while on OBD1, then upgrade to OBD2 and get a tune. But I wasn't sure how an OBD2 PCM could control the 46rh OD and LU, so I was thinking I would probably have to do a trans swap too. Then I found a MP OBD1 PCM part # P5249546, so I think I'm done with engine upgrades.

Let us know how that MAP sensor replacement works out for you!

Yes, this was the article I read a while ago. Thanks for finding it. From my understanding, the Hughes intake is a licensed copy of the Edlebrock Air Gap so performance should be similar.
Yeah, while I'm waiting for the MAP sensor I figured I would fix some wiring problems. The fuel level and temp gauge voltage regulator was getting constant power, so I rewired it to switched/Run power. I want to switch the power to constant for the headlight warning buzzer in case I leave the lights on, and I have the constant and switched power backwards for the radio. Minor problems, but 2 of the 3 required pulling the speedometer, which means removing the the steering column.
