That's normal over on lxforums, I think something was holding back mopar's charger from a decent time.
When our 6 & 8 were both stock.... from a dead stop I would take it about a half car till about 95 where she would pass me and keep slowly pulling, I had just a little bit better tires (275/40 proxes to her stock) though. Thru the gears her midrange is stronger, but my top end pulled back on the 8.
Stock srt6 vs lightly modded srt8...read the video description and see here:

The film started right after the third honk and it jumped on me a bit, but not for long. After the video we put 285/30 proxes on the 6 and it could get a jump on my 275/40s off the line everytime.
I need to make another video because now we are even again with her Needswing CAI added vs all the mods I've done to my SRT8. Same story as stock, the 6 pulls me midrange thru the gears and I pull back on top end.
The $ per horsepower gained on the 6 beats the 8's anyday though, no question about that...
