Gear change
I have a streetrod with a 2009 LS3 corvette engine. The tranny is a 4l60e. The rear is a Ford 9" with 3:70 gears.
I may be switching to a more friendly highway gear ratio. Does this change require a computer re- program. The car is
using the 2009 LS3 harness. Thanks, New to forum

2. 3.70 gears aren't "street friendly"? Really?
