Chipped 3.5?
 

Has anyone chipped their 3.5 liter? I see some sponsors advertise chips, I'm wondering if the chip for the 300 would also work in the Pacifica 3.5, it looks like there is no difference in the tuning from the factory.
Thanks for any comments, expert opinions, or ideas on how to get a little more oompf for the much heavier Pac.
