What can I do to make my ls430 feel faster? If they just put a decent torque converter/gears from the factory the car would be perfect. Instead they went the old geezer route, which is okay, but I'd like a little more pep?

Are there free mods, or small things you can do to get some power? This is an 04 ls430.

 

I don't know of any free mods but you can get an better air intake & exhaust. system
