Well, I received my DiabloSport Predator Tuner a few days ago and thought I would take it to the Dyno today for a before and after. Well there was an increase of 40hp and 46 ft-lbs of Torque. I went from 261.79 to 301.56hp and 304.63 to 351.17 ft-lbs torque. I think I like this increase.
I just didnt think that the HEMI 5.7L would have such low #'s to start. Is anyone else like this? I am running the K&N air intake, Flowmaster 40 and the Predator.
