I'm where you are....I bought a 100% stock, low mile GN years ago...and vowed to keep it stock. Then got kind of bored with it. Then got mad when I was challenged by cars a modded GN could have destroyed. So, I decided to do minor bolt ons that could be taken off easy and returned to stock if I wanted. I did the catback exhaust, the 3inch DP, ported exhaust housing, shift kit, Ultrachip(just for the anti theft feature really), bigmouth cold air kit, wider rear tires, scanmaster, airbag,hotwire kit....wasn't really impressed with this stuff, so now I'm gonna do a Razor alchy kit, TTchip, bigger injectors, fuel pump upgrade and then turn up the boost. My ultimate goal is mid to upper 11's.....so in the future I might do a TA49 turbo and PTE stock location intercooler and drag radials. All I can say is so much for keeping it stock!!!
