I ran against a friends 09 Audi S5 last weekend. My G8 has vararam intake, Doug Thorley LT's, x pipe in place of mid muffler, and Diablo Trinity tuner (no custom tune). His S5 has intake, Borla exhaust, and lots of suspension mods. Highway pulls were no competition, my car just pulled and pulled. He wanted to go from a dig. I figured the 46* weather and my bald stock Potenza's would see me losing to his awd, Michelin PSS's and tight suspension. Boy was I wrong. The pulls were on a long industrial drive-way. I beat him off the line each time and from there, obviously held the lead. If someone had offered him a gen 5 Camaro, he would have traded on the spot, he's now an LS convert. He's got some videos on a friends phone, I'll see if I can get them.
