1) Stage 1 Turbo Upgrade = New Bigger Injectors (for '03 GTs) + Entirely new PCM (engine computer)
2) Where should you get it? Not 100% sure, it's becoming harder to find.
3) How is it installed? Well the PCM is just a plug and play ... I've HEARD it's pretty simple. But with your car being an '03 GT, you'll need to install the newer bigger injectors too (04+ have new 'Stage 1' Injectors) I'm not sure how complicated the injector install is, but I'd bet it's difficult.
4) The HP increase is fairly significant --- I think an '03 GT with Stage 1 will be put up to 235 hp and 260 ft lb of torque at the crank...
5) Factory warranty --- How much warranty is left on your 03?! But yeah, IF the Stage 1 causes a problem (i.e. transmission, engine blows) then yeah -- you're warranty is NOT gonna cover it. But don't worry about warranties ... S1 is fun (so I've heard)
6) Fuel Economy is supposed to improve IF you can keep your foot off of the gas pedal at full throttle! But seriously, supposedly if you drive easy, it does increase fuel economy a LITTLE. (1 to 2 mpg maybe)
7) Does it give a noticeable punch? 100% Definetly (I don't have stage 1 b/c I can't afford it, but I've ridden in a GT with S1 and it's pretty fast.)
