IS 250 performance question
I have a 2010 IS 250 and I have some money saved up and I was wondering what would be the best upgrade for a little more power. I was thinking about getting headers and a tune but I'm not sure If there are any other options for power. If you could help me with this it would be appreciated!

My first suggestion to a -250 owner is always going to be a Y38 or Y50 differential. Having both tires applying power to the pavement makes an immense difference, both in the corners and in a straight line.
Edit:I meant Y38 or Y58. Y50 is the pegleg from an auto IS250. Y38 is 4.1 ratio, and Y58 is 4.3 ratio Torsen.
