i was having this problem to but i came to realize yer the v8 rumble is awsome but after i took the 6t for a spin i was happy with the outcome yer the v8 will put you into the seat straight away from a stand still but with the feel of an 6t from start you get kicked into the seat and when the turbo kicks in it pushes you in just that little more it feels like it craves more for punishment than a v8

only thing i have really felt different to the 2 is the XR8 feels heavier and more stable, but i did get a major hard when i took the XR6T for test run too
