I agree, nitrous explains the TQ figures here although that's a slightly higher number than I would have predicted at those HP levels under the "squeeze" - gotta love the juice!
Jeez, i never new Nitris improved torque so much. Thats a crap-load of torque. Without the graph i would have thought this was unblieveable too! lol. But i dotn have much experience dealin with Nos, so.
