I did some research and the Laguna stang, besides the porting job and mild cams ect, the rearend is packing upgraded 3.73s and the Z06 is 3.42s. The stock 2011 GT is 3.31. Put the 3.31s in and see how she holds up to the Z06
Just saying...
you come off a little butt-hurt with comments like these.
The Boss comes stock with 3.73's, therefore thats how it should be tested.
You seem to be over-looking the fact that a heavier, less expensive car is still coming out on top.
