04 GT 5 speed w/ magnaflow x pipe & cat back, JLT CAI. Like performance so far. Want better performance and HP. Looking for next mod but not sure where to go. Do not want to supercharge. Looked at a tuner then read an article that with the current mods I will not get much. Spent hour surfing the posting and now more confused. Looking for someone to set it straight. What are the best mods for the buck that will increase HP and better performance. Shifter? Springs? Tuner?... Thanks!
