AA Tune is a definite must have mod. For the money and convenience it is great. Now the next best mod is to put that new power down to the ground and no better way than an LSD. Had WaveTrac installed last week and this is a whole new car. Pulling into traffic now is more fun! No more spinning tires and lights flashing in the dash. Just git n' go! Dan @ Diffsonline.com did the install into his carrier and shipped the complete pumpkin to me and it is working great.
Can't wait for snow and the LSD!
