Not really sure about that. I put a pretty good hurtin' on my cousin with his 06GT (CAI, X-pipe, headers, and tune)...
I've have pulled on an srt8; it's prob. the cool 70 deg. weather along with methanol/water injection that's giving me all my timming and zero knock = a nice little beast.
U must didn't see the stage 2 at the end of my sig...
