hi, I have a 300 with the 5.7 . the car just hit 1000 miles. I don't know if its me or not but I swear the car seems slower than when I first got it. I recently installed a 93 octane tune with the trinity. throttle response is definitely better. not sure if I just got used to the car and the newness is wearing off.

Use your tuner to reset your TCM-transmission adaptives. That may wake it up a bit.

Old problem? Is the gas really at 93 octane or better that you are using? Have you checked your KR by data logging to verify everything is ok?

Maybe also try the 91 octane tune using 93 octane gas. Many of us felt it has better performance.

Knock Retard....BE CAREFUL; I wouldn't suggest adjusting that unless you know what you are doing, which I don't!
As Mix said, often people run 93 oct on the 91 OCT tune....I like that combo better. I doubt it's plugs or anything like that seeing your are just at a 1000 miles!!
Keep us posted, mate.

For me, running a HemiFever 91 Octane tune with 93 Octane fuel works very well.
