Would you NEED to probably not. I drove mine for a while like that without any trouble.

Well so much for that. I would have said yes. When I did my cam and heads I couldn't drive it with the stock PROM. It wouldn't idle and died at every stop light.

Re: Here's a mini ram question for you. (-=Jeff=-)
even on a stock motor a miniram will need changes to the wide open throttle air / fuel ratio.
the only way to know for sure is to do some data recording run's OR run it on a dyno with wideband O2 sensor.
the minram is designed to make more power above 4800rpm than the stock TPI manifold, so its more than likely going to run lean up there (not a good thing). however since the stock TPI does so well at lower RPM's (the air is moving faster,filling the cylinders more) the miniram will be running rich down there.
I imagine you'd be able to drive it around normally, but if you go WOT above 4600-4800rpm then your rolling the dice (with out tuning).
If you have an automatic trans the shift points will keep you from going real high (think they shift at 5200rpm) but to get the most out of a minram even that would need changed.
