1992 Dodge Dakota 5.2 Magnum advice

IMO, AJ nailed that to the wall.
The Hughesengines FI-AG is a real nice I take but the gains you get from it in what you have are marginal at best really. I’m sure a dyno will show a magazine eye popping rise in power ( sarcasm! ) but your not going to really reap the Potential benefits until you start swapping out cams.
Your basically leaving 2500 upstairs rpm on the table.

The TQ converter will hand out the best bang for the buck and have a instant gratification feel to it. If you intend to swap out a cam later, while talking to the converter people, let them know what cam you intended to use.
