They should. Chrysler is probably underestimating the numbers. GM did this in 1995 when they said that the automatic Camaro Z28 would do the 0-60mph dash in 6.2 seconds whereas in reality it did it in 5.8 which was the same times as the manual version (as the 4L60-E trans has a lower first gear planetary). I did this test in my girlfriend's 95 Z28 at the time and it did it in 5.8s. My 94 Impala SS was rated at 7s 0-60mph but I always got 6.5s as did Car and Driver magazine.
Look for serious acceleration times as a result of this limited slip.
In the case of the SRTs and R/Ts I would seriously make sure that if there is any torque management software inhibiting the transfer of full power to the rear wheels upon launching that it be removed by the user by way of a performance re-flash which MoPar Performance can offer and there is hi stall torque converters which they offer as well for the automatics (that T-handle full quadrant range shifter for the automatics would be nice too from Mopar perfomance/accessories).
If those two things don't solve the tip in/launch issues (if any as I haven't driven any Challys yet however I did drive 5.7L 300s and Chargers and they did exhibit soft tip in) I am sure that Hennessey or Hypertech will have something (such as a power programmer) that will solve the problem because, people, with 398/404 lbs ft of torque (5.7) or 420lbs ft of torque (6.1), there should be some neck snapping G-forces going on even at 4100lbs. Let's make full use of that telematics computer that calculates the G-forces in the dash (on the SRTs only I believe); which also calculates 0-60, 1/4 mile, horsepower and torque. This is like having a windshield mounted G-Tech device built right into the car's dash/instruments. I wonder if they use the same RISC processor.
