.413 thats what mine has

you have the 413 no wonder why you say you have so much more torque. how is it for top end? and what size tire you running.

I have stock tires on it right now, As far as top end with the setup i have in my sig right now it sits at about 54 mph, and i have power all the way up there. But as others have said about 45-48mph up to 54 takes a while.
