I'm thinking about getting the either the Trinity or Intune DCX. The only real mod on my manual 5.7 Challenger RT is a frankintake. Eventually I'll change the thermostat and maybe the headers. I'm interested in improving my MPG along with some extra power and tweaking some settings like the skip shift.

Since these tuners only come with the 93 and 91 octane tunes is anybody seeing a MPG increase to go along with the power increases?

What are you getting for HP Torque and MPG with the tuner?

Currently on two trips from Baton Rouge LA, to Jacksonville FL I'm getting 26.9 mpg without the intake and 24.9 with it.
