wan't to go faster with N/A speed density

I've heard that the heads and the intake could be fully ported, but the cam can't be change because it the map sensor to see to much vaccum. A guy told me that i could put an explorer intake with the stock ported heads, but you need an adjustable fuel pressure regulator and a rich/lean gauge to tune it. The speed density computer cause a rich mixture when it see to much vaccum wich cause driveability problem. That's what i've heard, correct me if i'm wrong.
