WOW!DV8, you da man.
I used to have a 93 6 speed LS coupe (black/black). I loved that car. Sold it to a good friend in 2005. He had it for a month, loved it, and then a 16 year old kid in a brand new 3 series BMW T-boned the Legend. The insurance company considered it a total loss.
I did everything I could think of (short of nitrous) - Dinan Stage II chip, RM Racing intake, Kone Engineering exhaust, and it got me a bit more - flat 6.0 seconds to 60 according to my GTech Pro.
I should have brought it to DV8 for what it really needed - a bigger engine.
I had a 2005 RL (rated at 300 HP) and never gave the car the respect it deserved because of my sense of loss for my Legend. I now have a 2009 TL (280 HP). I think the TL 3.5 would have been perfect for the Legend.
Congratulations on your great work DV8. The only suggestion I have for your car is .... how about some yellow tint for your windows?
