hey guys just wondering what you think i have a full header back in my 05 sunfire. with an aem coldair intake its quick but i want more. what would you invest your hard earned money in for some good hp. the turbo and supercharger is a lil pricey now but cams and injectors were on my mind...thanks
ur going to need tuning software if you do pretty much anything else to ur motor. cams, injectors, anything. take a look at the tuning forum. most people use hptuners.
