I disagree with Steve. The wavetrac was my favortite mod. Made the car handle so much better out of the hole. You can have all the power you want, but if it doesn't handle well, it isn't as much fun....especially spinning one wheel.... Not a fan of nitrous. Never will be, hp or not, times or not. I would look at manis and tune and save for a wavetrac.... 3.27 and TCU would be nice, but it would be my last mod.....good luck...
