Hey guys, I have been searching around for a bit and still can not come to the conclusion. I have a 2006 gs auto, with a few basic mods and a lot of love poured into her. I have a DC intake, slotted rotors, lightened wheels, tb bypass, basic stuff. I have just finished doing all the maintenance I wanted to do before I go more in depth into modding. Also disclaimer: I am a broke college kid who has to save up for at least a month before each mod (lol). Bottom line is I have plans for this car, but I do not want to continue without some sort of tune to get the most out of my hard earned cash spent on bolt-ons. The Fastworks tune sounds great, but I am not completely sure of the whole process, and am skeptical of sending a someone $500 for a service over the internet. The AEM F/IC also sounds great, but I do not know how to install it, nor do I have the knowledge needed to tune myself without risking destroying my engine through detonation. Anyone have an opinion on what I should do?
