Default Fuel pump rewire mod on a PT?

Here's a link to the fuel pump rewire mod for the Neon SRT-4's:

HOW-TO: Fuel Pump Rewire - Dodge SRT Forum - SRTConnection

They sell kits but I'm pretty sure this is the guide I used when I did it to my old SRT. Pretty straight forward and seemed to make a huge difference as the fuel pumps in those cars received a lower voltage than they should have and caused them to perform less than ideal. Whether it was an actual measurable difference or something that I just felt improved the overall performance of the car I was fairly impressed.

Now to my question, has anyone done this to their PT cruiser or are the fuel pumps in our cars already operating at an ideal voltage?

Increasing voltage supply to fuel pumps on EFI engines is an old modification for track run vehicles.

IMHO unless you are going to Track your PT and also consider a live fuel system then perhaps this may cause you more problems then the advantage for high engine speeds use gives you.

A easier thought would be to run an auxiliary inline fuel pump,regulator and return line (live fuel system conversion).

The only problem doing any of the fuel pump mods is how the PCM will react and what the AFR's and IAT's may change to?
