slow off the start
 
is it normal for these cars to be slow from the start when you hit the gas at a stop it is a dog for a couple seconds.

Others have stated there is a slight hesitation for the first several hundred miles or so, while the PCM "learns" the driving habits. Also on other vehicles I know with drive by wire, if you mash the pedal, the pcm will "step up" the throttle as a safety feature to be certain the drivers wants to go like he!!. See how it is after 3-500 miles. ENJOY;)

I put in the Predator tune yesterday and what a difference. I'm at 900 miles and the car came alive. Definately worth doing the 180 stat, cai, and tune. Now I know why Mopar2ya is always grinning:D

He has ZOOMERS and Mopar CAI, he is grinning because I let him drive my car which has K&N 180 stat Diablo tune and so much torque the grin remains....besides it is SILVER and we know what that means....:D

You probably need to tune the car (Diablo/Predator). Is your car auto stick? If so, hold the brake with your left foot and bring the rpms up for launching. Experiment to find a sweet spot.

I had that problem until about 600 miles. Now with the CAI, 180 thermo and Diablo tune, it's a whole new game.
