What it will do is shorten the gears but what you have to understand is that the tranny is set to handle speeds of like 155 to 160. So when we shorten them it takes away from the max speed. I have most of the tranny mods and I can hit 135mph. Your just taking away from your maximum speed. I actually felt more power when I was on the interstate.
