i havent changed the header because i havent yet decided whether to turbo or not. right now i am wanting to tune it slightly to increase performance but i am lost when it comes to air/fuel ratios and timing of the engine. I know there is a lot to be gained just by small tweaks because of the type of work that was done. but the question is where do i start? is it in fuel? do i need to change the curve? if so, how do i get the vehicle to the point where it isnt TOO rich. and what parts would be neccessary to do this. I have gotten a lot of answers, none of which i trust 100 percent. i had planned on a jwt ecu but here again, if i am unsure if i am going to boost, i would rather not spend the 500 bux on it just yet and didnt know if changing injectors, fuel pressure regulator, pump, mass air sensor, would be a much easier fix (not neccesarily all of the above, but a culmination of one or the other). could somebody please fill me in. whats gonna give me the best bang for the buck? Thanks!
