Yup, my 04' 350Z did the same thing...welcome to the "emissions control" era. Funny thing is, my Z was a "sports car," that drove like a "sports sedan" because of the drive-by-wire. It doesnt bother me much on the T4R, i mean, how fast do you really expect to accelerate in a 4000lb truck? Man, i wonder how much more different the T4R would run without all the fancy wiring and emissions gear????
