Well, you may not like my response but here's what I see and hear. First, it is an SRT6 not the cars you mentioned. Supercharged power is instant, therefore the torque curve is instant. The wheelbase is short, and it has an open diff. So, to control the instant power, you need good tires, which you don't have, you should upgrade to the posi trac rear end in order to get rid of the open diff responding differently each time you get on it. With the open diff, the traction control will try to kick in which can produce an unsure traction response, making the car a handful. Once I went to the wavetrac, both my cars handle predictable now...and more fun to drive...
