and your stock injectors will be good to well over 300 hp. after that you will probably need a bigger injector, but as of right now a dyno tune MIGHT get you a few extra ponies, but its not worth it until you have some sort of F/I or head/cam work. being an auto, if you build your transmission, then a tune is definetly worth it to take advantage of that, but youre a long way from being there lol. youll be fine =)
