I have the speed density setup on my '91 bird with the 3.1 and what I'm wondering is if any of you happen to know at what point I'll have to think about some mods to the computer. Currently I really only have the pacesetter headers installed plus some other minor things to get it up to 121whp, but I am planning on installing the intake I ported out in a couple weeks and am just curious what the stock limits are with this.

The only reason to upgrade you MAP sensor is when/if you go with boost. Your MAP sensor reads the vacuum in the manifold. So as long as there is not pressure in the manifold...you are good.
But depending on what else you do to your engine, there are other things in your ECM that can be tweaked to make things run better.

So I should be ok and not have to worry about any of that at least for now right?
