Agreed! Stock these cars have some knock. Flow mods, intake/exhaust will help lower the knock and then finish it off with tuning before you slap a pulley on.

If you don't want to spend money on a tuner then you should get a gauge to monitor, I prefer Aeroforce intercepter but they make some blue tooth ones that link to your smart phone. Do some research though because not all will display knock and some that do might not on some cars. Aeroforce is nice because it's on all the time I'm driving and you can set up warning lights so when it starts to see knock at whatever you set it to then lights come on to tell you to let off the gas.
