ok, so I have an 05 Magnum R/T and im a little obsessed with the HEMI. i like how the mds works on the freeway... but i also got a DiabloSport Predator tuner with the car.
i was curious if i could, if possible, make some adjustments that i can drive on the freeway with lower rpm(better mpg), without giving up too much power.
anyone have any experience with tuning the 5.7 HEMI via diablo sport??
