2013 Optima SX
13 Posts
Any ideas/opinions on what the best tune is that is a good compromise between reliability and performance for a '13 SX with no mods? I will most likely be installing dual catch cans. I'm not sure if I need to install different spark plugs (for some of the tunes) as I keep reading that the '13 Optimas have colder plugs. Any of you running with stock plugs on any of the tunes?
