My 2.0 jetta seems slower than it should be. Does unplugging my O2 sensor for the stock intake affect my performance? (i had to unplug it to put in my HP intake) Also what else can i do? my budget isn't great, but maybe theres some tuning i can do? or cheap upgrades? Also wondering if putting racing spark plugs will optimize performance, if so which should i get? thanks for w/e you guys can do.
