I am a proud owner of a 2004 40th annerversy GT. It has the many bolt on upgrades. Like a cold air intake, 85mm MAF housing w/Diablo Maf tunner, 75mm throttle body w/ 1/2in. spacer, Big mouth upper plenium, tower plus typhoon intake manifold, 2 1/2in. X-pipe w/ flowmaster 40 series mufflers, 3:73 gears, short throw shifter, and a SCT tunner (tunned by AmericanMuscle.com where I ordered it.) This car is my pride and joy. I am asking if anyone out there has any helping ideas to what I should do next. I am personnelly thinking fuel pumps and fuel rail kit w/ 24lbs. injectors. Keep in mind that I am trying to keep the car naturally asperated for now. To who ever has any helping ideas. Thanks for your time and help.
