Thanks davb673. Guess I should have qualified my question a little more. My bone stock '05 2500 with hemi and auto (2wd) is a gov surplus truck. I'm more interested in fuel economy improvements than increased power. I'm testing a Volo Performance FS3 "add on" chip right now with less than desirable results. So who gets the nod for mpg improvements, SC or Diablo? What about Hypertech?

Any details about your Taurus efan you can share?
