The timing and advance curves are set for low octane, ATX use. Not performance minded in the least.
What about the PATS?
There is absolutely no reason to go to a returnless fuel system. Not that it would even be very easy or cheap to do such!
PATS would not be an issue if he already has a PATS system vehicle. I am not aware of what car he has.
Now if you dont have PATS and your ading a newer pcm it will be a problem as the pcm will "look" for it and not see it. Making starting your car a problem
Now maybe you can trick it, it can be done, but I dont think their will be performance gain from this.
On a side note, you guys mention the fuel curve and timing with the 3L pcm. The SVT has to be a more aggressive program (anyone would assume this), additional output power has to be generated here as well. Think about it, a more aggressive pcm would be like a chipped Taurus.
