I was thinking Greddy or Haltech as they have direct plug-in kits. But Megasquirt would be an option. All are overkill I think. I have an email to Jet Chips to confirm reprogramming my stock ECU to run the 3.5L. Last I checked it was about $400 for their standard reprogramming on a Sport ECU. Can't imagine they can't do what I want. I'm trying to stay away from a bunch of esoteric modifications to make this work, though.

Wish I had access to the stock maps. I'm not entirely sure that the difference between 3 and 3.5 is enough that my ECU wouldn't be able to handle the difference without reprogramming.
