I recently purchased a 2011 Challenger SRT8 6.4-392. I am not going to go crazy on it (famous last words). Any way I added a Diablo tuner and a Dyno tune from a stock 392(like mine) from Hemifever out of NC. I have to admit the car was pretty strong stock but Sean from Hemifever really woke this thing up. Got rid of all the torque managment and also turned off the multi displacement mode, also made timing and fueling changes also. There is data logging on my tuner and he said he will "dial" me in after some 1320 ft passes Click below for a couple photos
My SRT8

So jealous. That color is awesome

Man...that's nice. I wish I had an srt 8 I just have an RT. I love the color, and the 392 rips.

Yup! That colour is pretty slick.

Very nice, I dig the color! Looks pretty close to my Daytona truck color.

lol yes it does. I like your signature quote "miss my 9 second runner"
