Who's the one with the KD BOX?
Other than 50lb ft of torque and 20hp, there is not much of a diffrence.
No pics sorry.
I think the install took all of 45 minutes... on a fairly hot engine & even cutting the notch in the plastic grommet/insert thing.
Just my 2 cts.
I consider the 550 for the additional power, and then the additional power I would put on it on top of that.... You know, so i could spank an E55.
