Most restrictive part would have to be the motor itself..
beat me to it.

if its a npi car, its the heads and if its a PI car, its still the heads just not as bad.
+1

The heads just don't flow well, ported or not.

Stock midpipe, or the stock tune. It is way too rich, advancing the timing, leaning it out a little bit will free up as much power as almost any other simple bolt-on.

Is there any way to advance the timing manually with our 4.6s, or must it be done through the CPU only? I know you can use a handheld tuner to advance the timing, but is there a timing adjuster on the cranck, etc., like on older cars? Thanks.

Yes and no. The 4.6's don't come with a timing adjuster, but they are available inexpensively from someone like Steeda.

ok...so how does one use a "timing adjuster"? How is practically handled? Do I have to remove the pulleys and expose the timing chain, etc.?
