Looking to tap into the brain trust on this one. TO ME, $10,000 to shave .6 seconds off an already absurdly quick 0-60 time isn't really worth it. If it's worth it to you, go with it, you'll get no judgement from me. But if luda gets me significantly better passing acceleration, say the 55-100mph bit, then it starts to make more sense. I drive on a lot of two lane highways with short passing lanes and getting around the RVs is crucial for my sanity. So, what have we heard about the big L in terms of passing power? Too soon to have gotten reports back from Model S P90D-L folks? Also, mods, please fix my title typo... it's Friday and I'm a little fried.
