hey guys, i have the drag gen 3 kit on my hybrid civic, i dont have upgraded injectors and a fuel pressure regulator, i was thinking of tunning the car, but many people have said that i would need something to adjust the rich and lean of the car, would i have to go with a vafc or something like that and get a fpr along with it? i've also heard alot about hondata and aem, but money's a issue, so would i need a vafc and fpr if i want to tune my car?
